The FZ LAU-97 70 mm rockets is the 70 mm fin-stabilised FZ LAU-97 rockets utilise the FZ-68 rocket motor which uses 3 kg of solid double-base propellant, extruded in a single grain with a revised geometry compared to other similar motors. The motor is intended to burn at a 'dual' rate which, combined with the multispiral grooved single exhaust nozzle and rearwards-folding fin assembly, considerably reduces the exhaust signature at launch and produces a burnout velocity of 715 m/s after a burn time of 2.3 seconds.
The complete motor weighs 5.7 kg and is 1.03 m long. The maximum range is 8,000 m which is reduced to 7,500 m if MK 40 rocket motors are involved. Time of flight to the maximum range is 45 seconds. The circular area of probability is 170 m. The FZ-68 rocket motor can be fitted with one of up to nine interchangeable warheads. These warheads can also be used with other types of 70 mm rocket. FZ-71 FRAG-HE This warhead, weighing 4.3 kg, may be considered as the standard for the series. On impact, its steel casing shatters into more than 8,000 effective fragments which are scattered over a lethal radius of 21 m. The nose-mounted impact fuze will function at a minimum impact angle of 5º. FZ-63 Incendiary Intended for producing screening smoke, as an incendiary or for target marking, this nose-fuzed warhead contains White Phosphorus (WP). Weight is 4.15 kg. FZ-85 PFHE This nose-fuzed warhead has a prefragmented warhead casing intended for the attack of light armour or soft-skinned vehicles. Over 3,000 fragments are produced. Weight is 4.3 kg. FZ-86 Smoke Produces thick screening smoke which is generated for more than 4.5 minutes after ejection during flight. Weight is 4.3 kg and length is 730 mm. FZ-100 Cargo Contains nine dual-purpose bomblets, each filled with 110 g of compressed hexogen and weighing 480 g. The shaped charge can penetrate 105 mm of armour plate and scatter anti-personnel fragments over a radius of 10.5 m. The impact-fuzed bomblets are ejected from the warhead after a delay-adjustable time fuze in the nose functions when the rocket is over a target area. This warhead weighs 6.7 kg and is 730 mm long.
