ALBATROS
L’ Albatros was one of six Aigle-class destroyers.
Introduction
I present here the Albatros.
It will be an exciting addition to the French tree in all its three configurations.
Most of the information here is sourced from French Destroyers: Torpilleurs d’Escadre & Contre-Torpilleurs 1922-1956 by John Jordan and The 2400-Tonners of the French Navy by Jean Guiglini and Kenneth R. Macpherson; both of which I highly recommend.
The history of the Albatros is in the comment section of this post.
From the bibliography and editor’s notes of the books I used, there might be some original documents and files on the Albatros in archives.
In my opinion, the Albatros will break the monotony created by the Aigle-class and Vauquelin-class having the same armament, and the Guepard-class and Le Fantasque-class having a similar main armament. This can be achieved by having the 1948 Albatros T 06 and 1954 Albatros D 614 between these ships .
Albatros introduces new weapon systems to the tree:
- The 105 SKC/33 Dop. L. C/37 which will later be featured on the CLs Châteaurenault and Guichen.
- The 100/55 Mle 1945 which will later be featured on the BB Jean Bart.
- The Canon 40 Mle 1951 will be making its first appearance in the French TT.
Albatros also carries some armaments that might be rare to find on the French BlueWater TT:
- The Canadian Boffin which wasn’t featured on that many French ships.

I believe it will be a good representative for the Aigle class on the tree.
Of the Aigle class, 3 of the 6 ships have been implemented.
- Of Series C (1927): Aigle, Vautour
- Of Series D (1927 Special): Milan
It would be nice to see Albatros, Gerfaut, and Epervier get added.
Cons
- Same weaknesses as the other Aigle class.
Other
- It has the French water-cooled Browning that had a faster fire rate than the Hotchkiss.
- It is a historic vessel that took part in the Battle of Casablanca.
Albatros T 06 (1948)

2*1 |
20mm Mk 7 Oerlikon guns |
1*3 |
550m torpedo tubes |
Speed: |

Pros
- The twin 105mm have a higher fire rate and come with AP, HE, and HE-TF.
- The twin 105mm turret has some armor, trains faster than the 138mm guns, and can rotate 360o.
- Two 75mm guns offer medium-range AA. Otherwise, they can be grouped with the 105s to increase the DPM slightly given that they have a cruiser-type plot and director .
- It has improved AA as compared to its 1942 configuration.
- It has improved systems.
Cons
- It has a relatively slow speed of about 27kn.
- It only carries 3 torpedoes.
Other
- It is unique.
- It changes the playstyle a bit.
Albatros D 614 (1954)
3*1 |
138.6/40 Mle 1927 guns (nos.1, 2, and 5) |
1*2 |
100mm Mle 1945 |
2*1 |
Shielded 75mm Mle 1924 HA |
1*2 |
US-style 40mm Bofors Mk 1 (Starboard) |

4*1 |
20mm Mk 7 Oerlikon guns |
1*3 |
550m torpedo tubes |
Speed: |
27.8 knots |
Pros
- The twin 100mm guns have a high fire rate of up to 25 rounds a minute.
- The 100mm turret probably trains faster than the 138mm guns and can rotate 360o.
- The 75mm guns offer medium-range AA. Otherwise, they can be used to improve the DPM slightly. The 100/55’s 855mps does match the muzzle velocity of the 75/50 at 850mps. I imagine this will make landing shots easier when they are grouped as secondary armament.
- The 40mm mle 51 has a better aiming system and might train faster than the Boffin.
- It has two extra Oerlikons.
- It has better radar and rangefinders than its 1948 configuration.
Cons
- The twin 100mm guns only fire HE and HE-TF.
- Unfortunately, the French radar employed isn't the most promising if I am reading [Military Wiki](https://military-history.fandom.com/wiki/French_battleship_Jean_Bart_(1940)) right.
- It has a relatively slow speed of about 27kn.
- It only carries 3 torpedoes.
Other
- It is unique.
- The 100mm gun has a lower velocity than the Japanese 100mm.
Aigle Class Destroyers
The 1927 naval estimates featured another ‘treaty’ cruiser (Foch), six contre-torpilleurs, five fleet submarines of the 1500-tonnes type, and the minelaying submarine Rubis.
The ships of the 1927 estimates reverted to earlier practice in being named after predators, in this case, birds of prey: Aigle (‘Eagle’), Vautour (‘Vulture’), Albatros, Gerfaut (‘Gerfalcon’), Epervier (‘Sparrow hawk’) and Milan (‘Kite’).
The contre-torpilleur, which made up the backbone of the flotillas in 1939, was often referred to as the “four-pipers” (‘les quatre-tuyaux’)
French destroyers were designed for cannon and torpedo attacks on Italian lines of communication.
Though they also had anti-submarine weapons in limited numbers but without dedicated sensors.
These shortcomings proved problematic when in the rapid and brutal raids in the Mediterranean, the Aigles and their colleagues found themselves having to escort ships in the Mediterranean and the Atlantic.

Hull and General Configuration
The weight-saving efforts in the Aigle-class’ design and construction succeeded.
The design for the Aigle class was drawn up under the supervision of Ingénieur général Antoine, head of the ‘small ships’ section (Section des petits bâtiments) of the STCN.
All of the previous types of destroyer had emerged from the shipyards slightly overweight. Weight saving was therefore an important consideration when the design for the Aigles was drawn up. There was a small but significant use of electric welding for the non-strength elements of the hull and superstructures, and this resulted in moderate savings of 50–60 tonnes. The designed meta-centric height (GM) was 0.80m vs. 0.68m in the Guépard class.
The hull form was also slightly modified. There was a reduction of 0.70 metres in the length between perpendiculars and 1.70 metres in length overall. The Aigle-class had a slightly deeper hull (+0.11m) with less freeboard than the Guépard: the height of the forecastle at deep load was 6.67 metres (vs. 7.09m), and the main deck was 3.8 metres (vs. 4.20m) above the waterline.
The construction methods employed for the hull were unchanged except for the limited employment of welding. The transverse frames had a standard spacing of 2.1 metres, but an additional watertight bulkhead was inserted close to the stern; the twelve main transverse bulkheads extended from the ship’s bottom to the upper deck and divided the hull into thirteen watertight compartments designated A–M. There were pumps rated at 100t/h in sections B–E and J–L, and these were doubled up in the main machinery spaces (F–I); the two narrow-end compartments (A, M) had smaller pumps rated at 30t/h.
The rudder was of similar design, but there were minor differences in the surface area for each of the ships: in Aigle it was 15.52m2, in Albatros and Gerfaut 14.3m2.
The ships manoeuvred well, although the turning circle remained excessive for a ‘small ship’ – a function of the comparatively high length-to-beam ratio and an underpowered rudder servo-motor.
The Sperry gyro-compass Sperry gyro-compass was the improved Mk VIII; Six magnetic compasses were also fitted.
All four ships were initially fitted with a CET 31 ultrasonic depth sounder.
Machinery
The machinery of the Aigle class was considered to be a major improvement on that of their predecessors: more robust, reliable, and economical, and with much greater flexibility of operation.
Aigle , Vautour and Albatros had Parsons Reaction turbines; Gerfaut, built by A C Bretagne, had Rateau-Bretagne impulse turbines.
The Parsons turbines of the Albatros comprised a single high-pressure (HP) and a low-pressure (LP) turbine working in series, with a separate cruise turbine clutched to the shaft of the HP turbine; the reversing turbine was on the shaft for the LP turbine and housed within the same casing. The HP turbine was rated at 14,000CV and the LP turbine at 18,000CV; the astern turbine was rated at 4000CV.
When going ahead, steam was admitted to the cruise turbine up to approximately one-tenth of maximum power (3200CV), then to the HP turbine and finally to the LP turbine.
The ship could steam at up to 18 knots on cruise turbines alone; the turbine could be declutched at low speeds, but it could be clutched to the shaft only when the ship was at rest.
During the 8-hour Maximum Normal Power (PMN) trial, which was undertaken at normal displacement, Albatros sustained speeds in excess of 37 knots.
Peacetime fuel bunkerage was 360 tonnes, a figure which rose to 540 tonnes (usable) at deep load. The provision of reserve feed water for the boilers was 128 tonnes, carried in side and bottom tanks. There was the customary 12 tonnes of fresh water for sanitation, plus 4 tonnes of drinking water for the crew in 500-litre tanks fore and aft.
Following trials, endurance was calculated at 4700nm at 15 knots and 3600nm at 18 knots on cruise turbines alone with two boilers lit. Much less would be achieved in wartime.
Albatros could cover 709 nautical miles at 39.153 knots.
The auxiliary boiler, which again was located to the starboard of boiler no.3, had slightly greater capacity; the heated surface area was 59m2 (vs. 52m2 for the model fitted in the Guépards).
The two turbo-generators, each rated at 80kW (106kW max.), were distributed between the forward and after engine rooms, as in the Guépard class. The two 22kW (26.5kW max.)
Bettus-Loire emergency generators were identical to those fitted in the earlier ships, and were located in the centre deckhouse.
Fire Director
There was a provision in the design for full director control with remote power control (RPC). In the event there was only director control for training; director control for elevation and RPC for training had to be abandoned.
Albatros was fitted on completion with a single SOM 3-metre coincidence rangefinder Mle B.1926 allied to the standard Mle 1923B electromechanical computer. With the FC computer Mle 1923B, only the angle of train (circulaire) is transmitted directly.
The angle of train was transmitted to the mounting via a Granat GD III receiver and the trainer, who was seated on the left of the mounting, aligned the pointers.
The two 75cm BBT searchlight projectors were fitted fore and aft with the after searchlight installed atop its own short tower abaft the mainmast; the control positions were fitted in the bridge wings.
Communications
The main wireless telegraphy office, the PC Radio, was at the after end of the bridge block, and the secondary wireless telegraphy office was located in the after deckhouse.
Boats
The boat outfit was disposed on athwartships rails between the first two funnels and on davits abreast the after deckhouse. It had the motor boat and motor launch onboard of the two 5-metre dinghies. The relative positions of the two boats on davits were also reversed: the 7-metre whaler was to port and the 7-metre pulling cutter to starboard.
Complement
Upon completion, accommodation is designed for 3 senior officers (Flight Commander and Commanding Officer, Second in Command, Chief of Staff), 7 junior officers, 2 first petty officers, 8 petty officers, 24 second petty officers, 163 quartermasters and ratings and 3 duty officers.
The regulation peacetime complement comprised 10 officers and 198 men.

It was intended to be armed with two 37mm single mountings of a new fully-automatic type with 2000 combat rounds plus 400 exercise rounds. The gun failed to materialize.
8mm Hotchkiss MG Mle 1914
The customary 8mm Hotchkiss MG Mle 1914, was to be mounted on pedestals on the forecastle. These guns were probably never embarked.

Work on the 138.6mm/40 Mle 1927 gun began in 1926. Proving trials were successfully concluded in March 1927.
The most significant innovation was the German-style semi-automatic sliding breech, which was much faster in operation than the interrupted screw breech of earlier French destroyer guns. The theoretical firing cycle was up to 12 rounds per minute; twice that of the Mle 1923.
The new 138.6mm Mle 1927 gun performed exceptionally well in service. The sliding breech was a success, and the gun had the high rate of fire the Navy had long aspired to for its fast flotilla craft.
A further modification that has attracted less comment was the lowering of the trunnions from 1.34m to 1.25m, making the gun easier to load at low angles of elevation. In order to achieve this it was necessary to sacrifice range. The maximum elevation of the Mle 1927 was only 28 degrees (vs. 35 degrees), and the maximum range, using the same ammunition as the Mle 1923, was only 16,600m compared with 18,200m for the earlier gun.
The ammunition chutes outboard of the 138.6mm gun mountings for the shells emerged to the port of the guns and those for the cased charges to starboard.
The regulation peacetime ammunition provision was unchanged at 100 combat rounds per gun, for a total of 500 shells plus 85 star shells. The electric hoists were each capable of supplying a maximum of 20 rounds per minute for each pair of guns, 6 which meant that they were barely able to keep pace with the firing cycle. Albatros, therefore, depended even more heavily than previous classes on ready-use racks during the early stage of action.
There was sufficient ready-use stowage for just over two minutes of continuous fire (four minutes for no.3 gun), during which time the racks would need to be topped up from the magazine hoists.
75mm/35 Mle 1925
The 75mm gun would be fitted briefly in Albatros before being landed. Following trials on Albatros was disembarked in late 1932.
The location chosen for the single mounting was not ideal; arcs fore and aft were poor, and the isolation of the mounting from its magazine would have been a considerable handicap in action. In the end, it was probably decided that the dubious military benefits of the gun did not compensate for the additional topweight involved.

Torpedoes
The torpedo outfit comprised two triple axial mountings for six 550mm Mle 1923DT torpedoes.
Two of the new Mle 1929 fire control positions, linked to a Mle 1924 central fire control computer (type Patrie), were located in the bridge wings. The rangefinder for the main guns was employed to provide range and bearing data.
The Mle 1920 control position on the torpedo mounting was equipped with a Granat GC II receiver, and an on-mount operator aligned the pointers to train the mounting.
100/250 Depth Thrower Mle 1928
There were two depth charge chutes each with eight depth charges, and four depth charge throwers on the upper deck abaft the break in the forecastle.
The DCTs would be removed from Albatros shortly after completion to reduce top weight.
Albatros as of 1942
Communications
The wireless telegraphy outfit was upgraded during the late 1930s, the most significant addition being that of an SFR Mle 1937 VHF (OTC) tactical radio for bridge-to-bridge voice communication in 1937. A medium-frequency direction-finding aerial was fitted forward of the bridge, and a DF office was installed in the bridge structure.
The wireless telegraphy aerials were re-affixed to prominent supports fitted on the after funnel, and the after (4-metre) rangefinder was raised by 0.75m to compensate for the height of the new platform.
Depth Sounder
During the mid-1930s the CET 31 ultrasonic depth sounder was replaced by a CET 32 Mod.1935. CET 32 gave particularly good results: up to 200 metres at a speed of 17 knots.
Searchlight
During a major refit in 1941, two 75cm searchlights were installed on a platform forward of funnel n°3.
A third, smaller 60cm projector was fitted on the foremast platform replacing a 75cm searchlight.
Rangefinder
Albatros was fitted with a 4-metre S rangefinder in the after end of the protective bulwarks for the after hoists during the mid/late 1930s, but with a lighter protective housing, and from 1937 all four ships would receive the new 5-metre stereo rangefinder turret forward, in place of the original 3-metre model.
Concentration Dials
Concentration dials were fitted in the Aigle-class from 1933, in response to a directive dated 7 October. The dials were initially painted white, becoming black in 1936. The arrangement adopted in the Aigle class was a departure from previous practice.
In place of the single after dial (initially fixed, then trainable), which in earlier ships had been fitted atop a platform abaft the mainmast, there were two fixed to the after ends of the bridge wings, which were extended and angled at 45 degrees to accommodate the dials and their winding machinery. This proved to be a far better solution, and the practice was extended to all subsequent classes of torpilleur and contre-torpilleur.
ASDIC Type 128 (Maybe?)
The 4 depth charge throwers were disembarked in late 1932. Two would be replaced following the outbreak of war in 1939; although these may have been removed after the Armistice; they were not on board Albatros at Casablanca in November 1942.
Faced with the slowness of the development of a French detector, the French Navy placed an order for British Asdic (called Alpha Devices in France).
A certain number of ASDIC sets were ordered in Britain after the outbreak of war, to alleviate our lack of anti-submarine detection gear. These were of Type 123 for smaller craft and Type 128 for torpedo boats and destroyers.
Albatros is thought to have had an Asdic 128 installed between June and September 1940, possibly at Oran. Aigle had yet to receive its when it was placed in care & maintenance under the terms of the Armistice in October of the same year.
In Jean Guiglini’s “2400-Tonners of the French Navy” it states that the installation of the ASDIC sets proceeded on a certain number of ships after the armistice: including the Albatros (1942).
Complement
A directive dated 10 May 1933 established the wartime complement as 10 officers and 217 men: two CPOs, eight POs, 25 POs 2nd class, 179 seamen, and three civilians.
The requirement to provide individual cabins for two Chief Petty Officers dictated a small revision in the layout of the accommodation.
On the whole, the crew considers their premises spacious and well-ventilated. The 227 men were distributed throughout the boat but contrary to what would become the norm after the war, the sailors were not necessarily housed near their combat station, the officers being housed at the rear, and the rest of the crew at the front.
The forward deckhouse had four bedrooms (officers and chief petty officers), the forward part of the main deck which constituted the teugue under the foredeck housed a crew station which was almost at the bow, with only an equipment hold separating it from the outside.
Aft of the main deck, the accommodation deck was bisected by the propulsion compartments. The forward part included two crew stations aft, the room for an underwater detection device, the telepointing room and another crew station.
The rear part was divided into three slices. The one adjoining the rear engine was occupied by senior officers. On the starboard side were the apartments of the commander and on the port side were the rooms of the second in command and the chief of staff.
The next section included five bedrooms for junior officers and the saloon. The last section was occupied on the starboard side by a bedroom for three civil servants quickly transformed for 2nd class ensigns.
The officers were therefore installed aft according to the tradition of the time on the accommodation deck with the three senior officers occupying a full section aft of the engine compartments.
The captain had an office bedroom and a dining room with a galley on the starboard side, while the other side is occupied by a bedroom for the chief of staff and an office bedroom for the second in command.
The aft section housed five officers’ bedrooms and, on the port side, the junior officers’ wardroom. Two officer bedrooms were installed in the forward deckhouse and the captain had a watch bedroom on the navigation bridge.
The masters and chief mates were installed in two adjoining stations on the starboard side of the main deck under the gangway block and the foredeck. The second masters had hammocks while the masters had berths, superimposed by two. The two bedrooms for the first two masters were located in the forward deckhouse on the port side of the officers’ bedrooms.
The quartermasters and ratings were distributed among four posts. A first position is installed on the main deck under the foredeck, but most of the men were accommodated in three positions placed forward on the accommodation deck. It was actually a large post divided into three watertight bulkheads. Quartermasters and deckhands had hammocks.
Meals were taken at the post, one sailor fetching the meal from the galley, another the bread and wine from the lazarette.
The infirmary installed on the main deck at the back of the forward part included four bunk beds by two, an inspection room, a bathroom and WC.
The destroyers had four kitchens installed in the main deck deckhouses with one for senior officers, one for junior officers, one for petty officers and one for the crew.
Other
Beginning in 1939, trials of replenishing escort ships (torpedo boats and destroyers) at sea by larger ships were carried out, both in line and alongside. The destroyers were then furnished with special installations for the purpose: a coupling and oil pipe in the bows; a point of attachment for a towing hook; and new fairleads.

Installation of loading slides to the guns.
The installation of the circular slides entailed a modification in the supply of shells to Nos. 3 and 4 guns. Viewed from the outside, this revealed itself in a new shape of blast screen to the shelters of these guns, and their extension upward to better protect the shell-handlers from the muzzle blast when the guns were fired on the maximum forward bearing. In addition, Nos. I and 5 guns also received circular slides, but that of No. 5 was removable to permit, in peacetime, the use of the entire quarterdeck.
The ammunition chutes for the 138.6mm guns were modified during the mid-1930s, the projectile chutes for guns nos.1–4 being extended to fully encircle the mounting. The chutes for no.5 gun continued to be stowed in the broken-down condition.
37mm Mle 1933
A platform for a twin 37mm Mle 1933 mounting and two 1-metre rangefinders was constructed above the after hoists.

13.2mm/76 Mle 1929 Hotchkiss
From 1933 Albatros was fitted with two twin 13.2mm Hotchkiss machine guns (CAD). These were initially fitted on the upper deck, directly abaft the single 37mm guns, and 1-metre stereo rangefinders were located at the forward end of the centre deckhouse to supply range and bearing data to both the 37mm CAS and the 13.2mm MG.
In 1939 the 13.2mm CAD would be relocated to a platform forward of the bridge, atop the forward 138.6mm hoists. The 13.2mm Hotchkiss CAD were relocated from their current position above the forward hoists to the forward end of the centre deckhouse, the position vacated by the 1-metre RF.
Albatros, which was in refit at Oran 11 June–5 September 1941, retained its 13.2mm Hotchkiss CAD above the forward hoists.

The 13.2mm CAD was a reasonably effective weapon against the relatively slow-moving biplane aircraft of the early 1930s. It had a range in excess of 2000m and could deliver 450 rounds per gun per minute. However, the 30-round magazine provided only four seconds of fire before it needed to be replaced, whereas twelve seconds of continuous fire was reckoned to be necessary in order to disable an aircraft approaching at 600k/h at 2000m.
13.2mm Browning
Albatros had 13.2mm Browning CAS fitted in rear angles on the bridge wings.
Only Albatros, Gerfaut and Vautour received two machine guns.

In order to provide continuous fire from the 13.2mm Hotchkiss MG studies were undertaken of continuous feed belts to replace the 30-round magazines. However, the main issue was the shortage of light AA mountings.
The Mle 1929 was no longer in production for Hotchkiss at their Levallois factory, where work was now concentrated on anti-aircraft gun mountings for the Army. The Navy, therefore, turned to the Fabrique Nationale d’Herstal (Belgium), which was producing the American Browning 0.5in (12.7mm) machine gun under licence. A contract for 361 guns with the firing chamber modified to accommodate the standard French SFM 13.2mm round was signed on 10 July 1939, with the delivery of the first guns specified for January 1940. At the same time, 500 mountings and sights were ordered from Italy.
The Browning MG used continuous feed belts, and in theory, could deliver up to 1000 rounds per minute – more than twice the rate of fire of a single 13.2mm Hotchkiss gun. It would become available in increasing numbers in 1941 when many mountings would be fitted in French destroyers and cruisers during refits at Toulon and in North Africa.

Gun Directors
The main guns were controlled by a new bulky telepointer for sea targets, fitted with an A/BM (British Type 275) Fire-Control radar at the after end of the bridge.
The 75mm guns were directed by a cruiser-type HA director. The two boilers in the forward boiler room were removed and replaced by a cruiser-type HA plot; the director itself was located atop the forward deckhouse in place of the forward pair of funnels.
In place of the former tripod foremast there was a lattice mast similar to that fitted in the Le Fantasque’s, carrying the standard US small-ship air and surface surveillance radars:
- SA, (later upgraded to SA-2) whose aerial was in the form of a rectangular grille, at the masthead
- SF (thimble radome) on a platform below, protected by a “bell-glass”-shaped radome.
- There was also an Americal SJ-1 surface search radar atop a post forward of the bridge and a 20m2 combat information centre (Central Information, or CI) directly behind the navigation bridge. It served also for torpedo launching.
- One IFF (Identification, Friend/Foe) radar.
- One artillery radar.
On and around the centre deckhouse were six open rangefinders for training: two with a 4-metre base (upper deck abeam funnel no.2), two with a 2.5-metre base (between the funnels), and two with a 1.5-metre base in place of the aft torpedo tube mounting.
Boats
The outfit of boats showed little change from the one with which the ship entered service: a 7-metre motor boat and a 7-metre cutter and two 5-metre dinghies (one motorized) on rails and crutches atop the forward deckhouse, and a 7-metre motor launch and a 7-metre whaler on davits abeam the after deckhouse.
Searchlight
A 75mm projector on a platform located between the two funnels.
Funnels
The two remaining funnels now were closer together than originally, number 4 (now number 2) having been moved forward about a meter so as to leave more room for the 75mm AA gun installed astern of it.
Asdic
Albatros, which still had elements in 1946, landed them because they were in too bad a state.
The project to embark on a new sonar did not come to fruition.
Other
The officers’ and POs’ galleys were relocated from the forward to the centre deckhouse, with new galley pipes running up outside the remaining pair of funnels. The engine room workshop, which was originally in the centre deckhouse, was moved to the forward deckhouse.

It retained three of its original 138.6mm Mle 1927 guns occupying the original locations of Nos. 1, 2 and 5 guns, furnished with “leather breeches” at the point of emergence from the shield.
2-Inch mk. 2 Rocket Launcher
A 2 in. rocket-launcher, Mk II, attached to the shield of Albatros’ No. 2 gun. Four lockers, each holding sixteen rockets were located adjacent, two on each side of the deckhouse.
Now, Gaijin can implement these if they choose to. They seem to have been primarily used for illumination but they do seem to have a HE contact rocket. It won’t do much so I won’t mind if they are not implemented. They will not be useful in the game.
In 1940 when the German “blitz” began, two antiaircraft rocket weapons were introduced into service use, the 2-in. U.P. (2-inch Unrotated Projectile) and the 3-in. U.P. These consisted of high explosive heads fitted to a standard type, fin-stabilized rocket motor, and fuzed with impact or pyrotechnic delay aerial burst fuzes.
The basic 2-inch rocket was a simple conventional device using a single stick of SCRK (solventless cordite) propellant which was electrically ignited. A nose-mounted No. 720 fuze was a direct-action wind vane armed device with a built-in self-destruct timer which operated after 4.5 seconds at a height of about 4500 feet (1372.5 m). The motor burned for 1.2 seconds and was launched after burning for 0.1 seconds. Without the self-destruct mechanism the rocket could reach 10000 feet (3050 m).
At charge temperatures between 40° to 50° Fahrenheit the British 2-inch rocket, which was originally designed as a ground- or ship-based anti-aircraft weapon, and later used as an aircraft rocket.
It was fitted with a high explosive (HE) warhead had a burning time of one second and a maximum velocity of 1,580 feet per second.

This flare is used to illuminate enemy targets at night. It is used in conjunction with medium-calibre guns. A flare launcher is mounted on either side of the gun shield at a fixed angle of 30 degrees. This arrangement makes it possible to keep a target illuminated and at the same time engage it with the main armament.
105mm C/33 Dop. L. C/37
Albatros mounted an ex-German 105mm LC/37 twin HA gun mounting, which was installed at the forward end of the after deckhouse.
This model 1937 AA weapon had three aiming axes, and could be aimed either by the director for the 138s or that for the 75s. To avoid any interference with this platform, the height of the flanking davits was reduced from 4 to 2.6 meters.
These are on the new mounts fitted on the Bismark class. They train the gun a bit faster and have a slight boost in armour thickness.
The 10.5cm Dopp LC/37 had a larger shield and the back was not inclined. The C/31 series can be distinguished from the later Dop. L. C/37 by their shorter shield and by the C/37 having a partial shield over the gun breeches.

40mm/L60 Bofors twin Mk 1
Initially, there were to have been two 40mm Bofors twin Mk 1 mountings of US origin – the model mounted in the four surviving contre-torpilleurs of the Le Fantasque class – in tubs at the forward end of the centre deckhouse.
In the event, only one was fitted. In the starboard barbette: a twin Bofors mount (taken from the light cruiser Le Malin), directed by a standard US Mk 51 director equipped with a Mk XIV gyroscopic sight.

The Mounting Mark V (Mark VC for Canadian-built examples) for the 20 mm Oerlikon and QF 2-pounder guns was also adopted initially as an interim mount for the Bofors. It was a single-barreled mounting with hydraulic power, and was known as the “Boffin”.
The Bofors 40mm/56.25 gun, was used widely during WWII and long after, on a variety of different mountings.
Although frequently listed as being 60 calibre, this gun was actually 56.25 calibre.
The Mk.VC Boffin mounting has undergone various modifications over the years, and the mounting that is installed on the Kingston class MCDVs looks considerably different from the original Boffin mounting.
The current mounting has had part of the left side cut away and a new clip rack (which looks similar to that found on the Mk.7 mounting) added to the left rear of the mounting. The original clip rack was horizontal and attached to the right side of the mounting.
20mm Oerlikon single guns on Mk 7 Mounts
Two 20mm Oerlikons on single Model 7a mounts were fitted forward of the navigating bridge, in the positions formerly occupied by the 13.2mm Hotchkiss guns.
550m torpedo tubes
A triple 550mm mount, Model 1300/1180 (a more modern model), originally destined for Bison (ex-Flibustier), was set on the original emplacement forward.
The aft TT was removed.
Albatros as of 1956
Gun Directors
The original HA director was replaced by a German-style triaxially-stabilised model, allied with the French-developed ACAE radar (Artillerie Contre Avions Eloignée -long range anti-aircraft artillery) – the installation of the latter was completed only in September 1951.
In 1953 the American SJ radar by the new French DRBV 30 navigation radar, which now occupied a small platform above the tiny SF thimble radome.
In a short refit early in 1954 the A/BM FC radar by the new French DRBC 11A, the antenna for which was fitted atop the main gunnery director.
Finally, in 1956, the American SF radar was removed.
Boats
In 1953 the davits for the 7-metre whaler and cutter were moved forward to protect them from the blast of the 100mm.
Other
At the beginning of 1951, little shelters were installed under the 40mm barbettes.

In a refit that took place from January to April 1951 the twin 105mm was replaced by the prototype for the new 100mm Mle 1945 twin mounting intended for the battleship Jean Bart.
At the beginning of 1953, the prototype 100mm was replaced by one from regular production.
The shells are refered to as contant or timefuze so I believe that they do carry HE contact shells.

At the beginning of 1953, a prototype Mle 51 hydraulic model was put in place of the Canadian Bofors 40mm Mk 1.
In a short refit early in 1954 the 40mm Mle 51 prototype was replaced by a production model.
I am not sure about the train speed of these mounts. I have been unable to find it stated anywhere. The Trident class of patrol boats carry the same gun and one has been passed to suggestions.

The 40mm CAS model 1951 gun used in the French Navy is a national adaptation of the 60-caliber gun (the famous 40L60). It naturally made its appearance in the French Navy, at the end of the 2nd World War, through ships sold under the Marshall Plan.
The implementation team includes 3 people:
- The gunner seated on the left;
- The provider standing behind the breech in the hoop;
- The head of the room in the background.
Maneuvering the gun is done hydraulically (a small 115 volt motor drives a hydraulic pump) by the gunner with the control stick in front of him.
For pointing the target, he uses an optical sight in which appears an alidade allowing him to adjust his shot. This viewfinder appeared in recent years is common to 20mm Oerlikon and F2 guns.
Firing can be continuous or piecemeal. The barrel is fed manually by the loader who introduces 4-cartridge blades into the breech. A waiting park is located just to its right. At the end of the shot, the empty case is ejected on the front of the part via a guide starting from the underside of the breech. In the event of a breakdown, a crank can replace conventional controls.
20mm Mk 7 single Oerlikon guns
In January 1952, two new single Oerlikons were installed on the fo’csle.
