Brazil’s GESPI finalises new 70 mm air-launched rocket

16 November 2017

Brazil’s GESPI Defense Systems has finalised development of its self-funded 70 mm/2.75 inch calibre Strike-70 unguided air-to-surface rocket.

The certification phase of the Strike-70 was completed on 31 October with an undisclosed number of firings conducted from a ground-based LAU-68/A rocket launcher – supplied by the Brazilian Air Force – at the Brazilian Army’s Agulhas Negras Military Academy in Resende, in the state of Rio de Janeiro. Development of the Strike-70 was initiated in September 2016, and the weapon is now fully ready for serial production, a GESPI spokesperson told Jane’s .

Intended to equip fixed-wing and rotary-wing platforms, the Strike-70 is designed to be compatible with existing launchers such as the LAU-68/A, LAU-3/A, and LAU-131/A, or similar systems capable of firing 70 mm Hydra-70 and SBAT-70 rocket types.

With a stated range of 9 km and a maximum speed of 812 m/s, the Strike-70 is 105.9 cm in length, and comprises a 6.7 kg GMK-66 rocket motor (developed by GESPI) with double base propellant, and three wrap-around fins for stabilisation. The Strike-70 has a shelf and service life of 10 years and can operate in temperatures from -45°C to 65°C.

GESPI is offering three warhead types, developed by AEQ of Brazil, for the Strike-70: the 2.4 kg CAB 70 EX practice warhead – designed to simulate the launch characteristics of a rocket armed with a high-explosive warhead; the 3.8 kg CAB 70 AP anti-personnel warhead that is effective against fixed and mobile soft and hard targets and initiated by an EOM-FAP fuze; and the 2.6 kg CAB 70 AC anti-armour warhead, designed for use against main battle tanks and armoured vehicles.
