Fives-Cail Babcock launches FL-20 turret

THE FRENCH company Fives-Cail Babcock's latest turret, the FL-20 105 mm, will make its first public appearance at Satory this year. The company has been involved in the design, development and production of turrets for 40 years, and JDW recently paid a visit to the company's headquarters in Paris to be briefed on both the FL-15 and FL-20 turrets.
Turret design
Under contract to DEFA, Fives-Cail Babcock built its first FL series turrets shortly after the end of the Second World War. The first turret to be placed in production was the FL-10 armed with a long barrelled 75 mm gun which was installed on the highly successful AMX-13 tank which entered production at the Atelier de Construction Roanne in 1952. This turret, like all other FL series turrets, is the oscillating type in which the gun is fixed in the upper part of the turret which in turn pivots on the lower part. In the turret bustle are two revolver type magazines, each of which holds six rounds of ammunition. After the gun has been fired the empty cartridge case is ejected out of the turret via a trap door in the turret rear. Over 2000 FL-10 turrets were built, many of which remain in service. The FL-11 turret is similar in concept to the FL-10, but with turret bustle and its two six-round magazines removed; this was installed on the Panhard EBR (8 x 8) heavy armoured car, still used by the French Army today, and a few AMX-13 light tanks used in North Africa. With the removal of the semi-automatic loading equipment the 75 mm gun had to be loaded manually. While the 75 mm was an excellent weapon, it was decided to rebore this to 90 mm and all French Army tanks were subsequently modified to this standard, which remains the current model for export. The 90 mm gun, with thermal sleeve, turret clearly showing commander's and gunner's on could fire four types of ammunition: canister, high explosive, high explosive antitank (HEAT) and smoke. The HEAT round would penetrate 320 mm of armour at 0°. More recently, GIAT has developed an armour piercing fin stabilised discarding sabot (APFSDS) round which will penetrate a triple target at an incidence of 60° at a range of 2000 m. The French Army has some 800 AMX-13 light tanks in service with FL-10 turrets armed with 90 mm guns. The FL-12 follows the same principles as the FL-10 but is armed with a 105 mm gun which fires the same projectiles as the GIAT AMX-30 MBT; the ammunition is, however, shorter as a less powerful charge is used and therefore a lower muzzle velocity. Production of the FL-12 turret was finally completed in April 1984 after some 2000 had been built. In addition to being fitted on some AMX-13 light tanks built for export (including The Netherlands and Ecuador), the turret was fitted on all production Austrian Steyr SK 105 light tanks/tank destroyers produced for Austria, Argentina, Bolivia, Morocco and Tunisia. For trials purposes it was also installed on the ENGESA EE-17 Sucuri (6x6) tank destroyer, which never entered production. In June 1983, Fives-Cail Babcock announced
