ERC 90 F4 Sagaie 2
(Prototype 2)

TL;DR: Second prototype of the ERC 90 F4 Sagaie 2, an improved version of the ERC 90 Sagaie, featuring a stabilised 90mm CN 90 F4 cannon, as well as an improved hull and mobility

Note:
The ERC 90 F4 Sagaie 2 was never adopted by France. The only operator of this variant is Gabon — however, this suggestion is specifically for the second prototype, differing only slightly from the Gabonese model. See Conclusion for my suggestion on how they can both be implemented

History
The ERC (Engin de Reconnaissance à Canon) is a six-wheeled French armoured car developed by Panhard. It was designed as a heavier, six-wheeled alternative to the AML (automitrailleuse légère). Development began in 1975, on the basis of the company’s new 6x6 APC, the VCR (Véhicule de Combat à Roues). The VCR / ERC family was first shown in 1977 at Satory VI. The ERC was offered in two main armed versions (alongside various support and anti-air variants): the ERC 90 F1 Lynx and the ERC 90 F4 Sagaie. The F1 Lynx variant mounted the Lynx turret, an improved version of the H 90 seen on vehicles like the AML 90. The ERC 90 F4 Sagaie (French for Assegai, a spear / polearm used by various peoples in southern Africa) was armed with the new TS 90 turret, housing a longer, higher velocity 90mm cannon.

The ERC quickly received attention, due to its promising design, and Panhard had already received mass production orders by 1977–78. The French Army tested the ERC 90 F4 Sagaie from 1978–80, and accepted it into service that same year. First deliveries were made in 1982, and 40 vehicles, out of an order of 176, had been delivered by 1985. The ERC 90 F4 Sagaie would go on to be exported to a number of nations, such as Côte d’Ivoire, Nigeria, and Chad, while the Lynx would see service in Mexico, as well as Nigeria and Argentina.

Back in the early 1980s, Panhard realised that multiple potential customers (such as Saudi Arabia) preferred automatic gearboxes and diesel engines, as opposed to the manual gearboxes and petrol engines of the VCR / ERC. As such, they began developing a new variant of the ERC and VCR, dubbed the ‘C’ range. In order to improve power-to-weight ratios while also saving weight, Panhard decided to integrate twin engines into the new vehicles. This resulted in the creation of the Sagaie 2 (sometimes written as Sagaie II instead) and VCR 2, both of which could be fitted with either two XD3T diesel engines or two PRV V6 petrol engines.

This improved hull was also the perfect opportunity to improve the firepower of the Sagaie. In 1983, Panhard had displayed a prototype of the Sagaie, fitted with a stabilised main gun in the TTB 190 turret. The increased weight put strain on the light chassis, and the power-to-weight ratio was deemed too low. The Sagaie 2 was first displayed at Satory X in 1985. While armed with the same TTB 190 turret as the ERC 90 F4 Sagaie variant displayed in 1983, it featured a new, longer, wider hull, in order to accomodate the aformentioned twin engines and cope with the new turret. Two prototypes had been built by 1985 — one with petrol engines, and one without. Details regarding the two prototypes (and whether anymore were built) are scarce, but based on the available information and images, it appears that the first prototype (henceforth designated P1) was fitted with the petrol engines. The second prototype (P2) was fitted with the diesel engines, as well as a newly designed ‘extra-low’ chassis, larger 13.00x16 tyres (believed to be retrofitted onto P1), and modified side bins.

What appears to be the first prototype of the Sagaie 2, as seen in International Defense Review 1/1985. Note the slightly different hull shape, lack of sidebins, and different smoke grenade configuration compared to the second prototype

The Sagaie 2 was offered in two other versions: an amphibious variant, with waterjets, or a desert variant, without waterjets. In the case of the former, the side bins would be fitted with foam, whereas they would be used for storage on the latter. Both P1 and P2 were built in the amphibious configuration. The two prototypes also had a number of minor differences between each other, not least of which were slightly altered turrets (P1 had four 76mm smoke grenade launchers on either side, as opposed to P2’s two 80mm smoke grenade launchers).

The turret — the SAMM (Société d’Applications des Machines Motrices) TTB 190 — is armed with a two-plane stabilised 90mm CN 90 F4 main gun. Two fire control systems were offered: the SFIM/OIP FCS, with a periscopic gun sight and an integrated laser rangefinder, or the SOPELEM FCS, with a mantlet-mounted telescopic gunner’s sight and an independent laser rangefinder. It appears that both prototypes were fitted with the SFIM/OIP FCS. At least one prototype underwent trials in Saudi Arabia in 1985, and was reportedly fitted with a thermal imager, although details on which vehicle and type of sight are not known.

While the Sagaie with the TS 90 turret was adopted by a number of countries, including France, the Sagaie 2, despite the significant improvements in performance, saw very limited success. The sole country that took interest in the vehicle was Gabon. Gabon bought six ERC 90 F4 Sagaie 2s, alongside four of the ERC 20 Kriss variant, armed with the TAB 220 turret with dual 20mm autocannons (it’s worth noting that the ERC 20s obtained by Gabon were mounted on the Sagaie 2 chassis, not the Sagaie 1 chassis as the French prototypes were). The six production vehicles differ slightly from the prototypes described here, such as in the addition of baskets on either side of the turret. They remain in Gabonese service today, alongside a plethora of other light wheeled armoured vehicles.

Meanwhile, P2 appears to have ended up at Musee des Blindes in Saumur, France, up until sometime in the 2010s, when it was then given to Arquus Defense and put on public display, where it remains today.

Characteristics
The ERC 90 F4 Sagaie 2 (P2) is fitted with the TTB 190 turret, armed with a two-plane stabilised 90mm CN 90 F4 cannon. This is the same gun on the MARS 15 in-game, and is also used on a number of other French armoured vehicles, albeit without a stabiliser. The CN 90 F4 is able to fire a number of different rounds, including OFL 90 F1 APFSDS, which penetrates 277mm @ 0° @ 10m (in-game figures), OCC 90 F2 HEAT-FS, which penetrates 350mm @ 0°, OE 90 F1 HE, which penetrates 18mm @ 0°, and OFUM 90 F1 smoke. 33 rounds are carried in total, 23 of which are in the turret. The turret is fitted with a semi-automatic loading mechanism: 10 rounds are stored in a ready-rack, 8 of which are in a manually-operated drum magazine that brings them close to the breech. 13 rounds are stored in a rear turret rack, and the remaining 10 rounds are stored in the hull. The semi-automatic loading mechanism is advertised as permitting a rate of fire of up to 10 rounds / minute (6s reload).

As secondary armament, the ERC 90 F4 Sagaie 2 (P2) is armed with a coaxial 12.7mm M2 HMG, for which 600 rounds are carried, and a roof-mounted 7.62mm (either AA NF 1 or MAG FN), for which 1200 rounds are carried. P2 is fitted with four 80mm smoke grenade launchers (2x2).

The TTB 190 fitted to the ERC 90 F4 Sagaie 2 (P2) is equipped with the SFIM/OIP fire control system. The commander has the day/night AERITALIA periscopic P 204 sight, with a fixed x8 magnification. The gunner is equipped with the LRS 5 periscopic day/night (second-generation light intensifier) gunsight, with x8 (day) and x4 (night) magnification. The FCS also includes a laser rangefinder, with a range of up to 9,900m. The TTB 190, as fitted to the ERC 90 F4 Sagaie 2 (P2), has an electric gunlaying drive, allowing for a maximum horizontal traverse speed of 35°/s. The gun can elevate from -8° to + 15° at 17°/s.

Prototype 2 as shown in 1985

The ERC 90 is lightly armoured — the hull protects against only small arms fire and shell splinters, and is around 10mm thick all-round. The TTB 190 turret, on the other hand, provides slightly better protection. It is frontally resistant to 14.5mm rounds, and resistant to 7.62mm rounds (at least) all-round.

The ERC 90 F4 Sagaie 2 has a combat weight of 10t. P2 was fitted with two XD3T diesel engines, producing 196hp total, giving it a power-to-weight ratio of 19.6hp/t. The ZF automatic transmission gave it four forward gears and one reverse gear. It could reach a maximum speed of 110km/h, and 7.2km/h in water. It carried three crew: a commander, gunner, and driver. The vehicle has a six wheel drive, but the middle wheels can be lifted with hydraulic suspension.

Conclusion
The ERC 90 F4 Sagaie 2 would be an excellent addition to the French tech tree, armed with a familiar 90mm gun but upgraded with a stabiliser, on a nimble wheeled chassis. It would likely go at a BR of 9.0. Prototype 2 differs only in minor details from the production variant used by Gabon, and could be added as a French-operated researchable counterpart to a premium / event Gabonese-operated production ERC 90 F4 Sagaie 2 (or vice versa).
