<h2>Armament</h2><p>70 mm 40-tube LAU-97 MRS; NDL-40 70 mm 20-tube MRS ( Indonesia ).</p><h2>Development</h2><p>The 70 mm LAU-97 MRS was developed during the late 1970s and early 1980s by the Belgian Forges de Zeebrugge SA (FZ). They produced a 40-tube light artillery rocket launch system designed to utilise the FZ-68 70 mm rocket motor and an associated series of warheads. The FZ-68 was developed with the objective of smoke reduction at launch, reduced corrosion effects, improved accuracy and a higher launch velocity, all compared to existing 70 mm aircraft rockets. The resultant 70 mm FZ LAU-97 rockets can be launched from helicopters as well as the ground launchers. The LAU-97 launcher can utilise rockets with MK 40 and other similar rocket motors but with a resultant reduction in range. In 1985, Industri Pesawat Terbang Nusantara Indonesia ( IPTN ), took out a licence to produce 70 mm FZ LAU-97 rockets and went on to develop its own 20-tube MRS, the NDL-40 . The scheduled complete development and certification phase for the NDL-40 was late 1994; the present status of this programme is now uncertain. The 70 mm FZ LAU-97 rockets are used as the subcalibre rocket component of the Royal Ordnance Reduced Range Practice Rocket ( RRPR ) system for the 227 mm MLRS (qv). Three ballistically matched warheads are involved for this role: indicating pyrotechnic with a strong signal in the visible and infra-red spectrums; HE (TNT) with an impact fuze; and completely inert.</p><h2>Description</h2><p>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-49 AP Up to 400 mm of armour can be penetrated by the shaped charge of this warhead while at the same time some 1,200 anti-personnel fragments are produced. Weight is 3 kg. FZ-58 HEAP This warhead is intended for use against any target which requires a degree of penetration before detonating and has a penetrating and anti-ricochet plug in the nose. A base fuze is fitted. Weight is 4.52 kg. 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. M257 Illuminating This warhead contains a flare assembly which is ejected from the warhead in flight and descends on a small parachute, providing 1 million cd for 120 seconds. Weight is 4.9 kg. FZ-32 Practice Produces a smoke cloud which lasts for 10 to 15 seconds after impact. Weight is 2.9 kg. Some references also mention Flechette and Chaff warheads but no information regarding these is available.</p><h2>Authorised fuzes</h2><p>See text Equivalent rockets INDONESIA</p><p>INDONESIA</p><h2>Manufacturer</h2><p>Industri Pesawat Terbang Nusantara Indonesia ( IPTN )</p><p>Type: FZ-68 rocket motor and FZ-71 FRAG-HE warhead</p><p>Description: Licence production since 1985 - current status uncertain, see text.</p>
