This is a Norwegian modified torpedo.
in tactical situations in Norwegian waters this was an advanced weapon for its time.

HISTORY
Both vessels were decommissioned as torpedo boats in 1931 and the torpedo armaments removed. They were converted to minesweepers, and as such they were both in service at the outbreak of war in Norway in April 1940 with a station in Tønsberg. On 11 April, HVAS was in Stavern when German patrol boats entered the harbor and landed soldiers who took possession of HVAS without a fight. It was later incorporated into the German navy and given the name SEESTERN.KJÆK, which on the night of 9 April patrolled the Oslo Fjord, entered Bolærne early in the morning and moored at the wharf in Kongshavnsund. Later, KJÆK was ordered to go to Tønsberg, where it arrived at 1500. On 12 April, KJÆK was taken over by the Germans without a fight.

The Germans incorporated KJÆK into the German navy under the name SCHILDKROTE. Both HVAS and KJÆK were returned to Norway at the end of the war, but never returned to service.

TORPEDO BOAT 2nd Class
In the years from 1882 to 1888, the first seven of the long series of new 2 class torpedo boats were built in quick succession. around the introduction of parliamentarism, there was great tension between the left in Norwegian politics and the king. The left saw the military as the king’s extended arm and there was little will to allocate money for new vessels. that funds were actually obtained for the torpedo boats can be attributed to the fact that they were far less expensive to build than gunboats, and that they fitted in well with the idea of an archipelago defence, which should only serve Norway’s interests. The basic idea was that they should be small and fast, so that even without being hit they could surprise larger warships, deliver their torpedoes, and retreat. other nations, not least Great Britain, had long since caught up with our lead in development and passed us by. Shipbuilding inspector Blom at Karljohansvern Verft thus had a lot to lean on when he led the development of our new torpedo boats. The challenge was that the steam engine had to be far stronger in relation to displacement than with some previous Norwegian-produced vessels. The shipyard, which had built several iron hulls since the 1860s, was now to build a steel hull for the first time. The coal-fired steam boiler was still a locomotive boiler and the piston steam engine was of the compound type. the launching of the torpedo boat OD in 1882, as the first steel boat, was thus a major milestone for the yard, and the joy was no less when it achieved a speed of a staggering 18 knots. then another six torpedo boats followed in succession, with gradually greater displacement, larger steam engine, but largely at the same speed. While OD only got a single torpedo tube in the bow, the next six got double torpedo tubes in the bow. the tubes lay above the waterline and the torpedoes were launched with compressed air or gunpowder. on deck they had a five-barreled rapid-firing 37mm revolver cannon. the first three Lyn, Glimt and Blink, had to change their names because the Swedes wanted to reserve the southernmost part of the alphabet as the first letter of their own torpedo boats. the new torpedo boats gained a reputation as being lighter and more maneuverable and with good seagoing properties. It could certainly be needed, because the comforts for the crew of 11-12 men were otherwise not great. Ahead of the crew’s boats, the torpedoes protruded into the room, and in addition they had extra torpedoes under the deck. after a few years of separate torpedo boat exercises, from 1887 they entered joint exercises for the coastal defense department. then the later commanders Børresen and Sparre each had their own torpedo boat. The tours were extended in both time and operational areas, but there were still only summer tours lasting a couple of months.

As is well known, the period of the Union ended with the left understanding that we had to strengthen our defense in order to strengthen our position in the Union, or get rid of it. after a break of a few years, there was therefore new momentum in the construction of torpedo boats. from 1894 until 1905 a further 17 torpedo boats were launched. only now were they designated 2 class torpedo boats, since we simultaneously acquired or built a larger type of torpedo boats. in between these, the navy yard also built a smaller torpedo boat which was given the descriptive name MYG (mosquito). the idea with this 3 class torpedo boat was that it should operate in closed waters and that presentation should be taken care of by an associated depot ship, but this one was left. for the new series of Class 2 torpedo boats, the enthusiasm was not as great. they were larger and certainly more comfortable, but even though they had a water-tube boiler and a more powerful steam engine, in the first half the speed was not any greater. they had been given a flatter stern, which resulted in a larger stern wave and poorer steering. from LYN in 1896, the one torpedo tube in the bow was replaced with a rotatable torpedo cannon on deck, so that one could aim more easily regardless of the vessel’s course. they were given two quick-firing single-barreled cannons. due to capacity problems, some of the boats were combined with other Norwegian shipyards. only with the last five before 1905 was it possible to get the speed up to 22-23 knots. after the dissolution of the union we got three more torpedo boats of 2 class, Teist, Skarv and Kjell. These had two torpedo guns on deck, and they were both larger and faster than the last boats of the 1st class. that they still chose to call them 2 class, I have found no better explanation than that they were a kind of “protest”, because they had really wanted even bigger torpedo boats
