Sagem, OIS-AT create AASM Hammer joint venture

IHS Janes

21 April 2016

French company Sagem announced on 19 April that it had signed a joint venture (JV) with Indian company OIS Advanced Technology (OIS-AT) that will allow the manufacture of components for the AASM Hammer precision-guided munition in India.

The agreement will have OIS-AT manufacturing bomb guidance and glide kits for the system in India, as part of the Indian government’s ‘Make In India’ campaign to promote defence equipment manufacturing in India.

Sagem added in a statement that the guidance and glide kits would be “customised to specifically meet Indian Air Force requirements”.

According to IHS Jane’s Air Launched Weapons, Sagem is understood to have been negotiating an AASM contract with India to supply weapons for Indian Air Force Sukhoi Su-30MKIs, upgraded Mirage 2000Hs, and upgraded SEPECAT Jaguar IS/IBs. Indian sources also stated that the AASM would be integrated on Indian Navy MiG-29Ks.

The AASM Hammer is a modular kit that adds a guidance/seeker assembly to the existing ‘dumb’ general-purpose aerial bomb, along with pop-out airfoils to increase the bomb’s gliding range. Additionally, a rocket booster further extends the bomb’s stand-off capability.

The baseline version of the system for use by the French military and for existing export variants is for use on a 250 kg (500 lb) bomb. Initial testing was conducted on a Dassault Mirage 2000N, with later tests taking place on a Dassault Rafale. It is currently cleared for use on the Lockheed Martin F-16 and Dassault Rafale, with Sagem having evaluated compatibility with larger platforms such as the Lockheed Martin C-130 Hercules, Lockheed Martin P-3 Orion, and the Dassault Atlantique 2 maritime patrol aircraft.

The 250 kg variant has a maximum range of 15-60 km, depending on the attack profile, and can use either a GPS, an inertial navigation system (INS) with imaging infrared seeker, or a laser seeker.

Armement Air-Sol Modulaire (AASM) HAMMER Air-to-Ground Missile

Armement Air-Sol Modulaire (AASM) HAMMER (Highly Agile Modular Munition Extended Range) is a new generation medium-range modular air-to-ground weapon designed and manufactured by Sagem (Safran group), for the French Air Force and Navy.

The AASM weapon system has a length of 3m and weight of 330kg, and has a range of over 60km at high altitudes and 15km at low altitudes. It has fire and forget capability, and an extended stand-off capacity.

The interoperable missile has the ability to engage multiple targets simultaneously. It can also strike fixed or moving targets with high precision. The missile is maintenance-free and has low lifecycle costs.

The missile uses single, double or triple store adaptors and uses Sagem’s Hemispheric Resonating Gyro, inertial / GPS hybridisation and strap-down infrared imagers and associated algorithms for conventional deep strike missions.

The AASM HAMMER missile consists of a guidance kit and a range extension kit. The kits are fitted with Mk82 warheads including Smart Bomb Unit (SBU)-38, SBU-64 and SBU-54. The easy to use missile supports operations with 125kg, 250kg, 500kg and 1,000kg bomb bodies, and can be reprogrammed during the flight.

The basic version SBU-38 HAMMER is provided with hybrid INS/GPS guidance, while the SBU-54 version is equipped with INS/GPS/IR (infrared) guidance. The latest version SBU-64 uses INS/GPS/laser guidance.

AASM INS/GPS

The hybrid inertial/GPS layout is the standard guidance mode for coordinates. Once the coordinates have been entered in the weapon, the inertial guidance system enable it to hit the target without requiring a GPS signal, if it is unavailable. This version is designated the SBU-38 Hammer (Smart Bomb Unit).

The AASM’s modularity allows it to be used on 125, 250, 500 and 1000kg bomb bodies. Its engine provides it with range greater than 50km, meaning it can be fired at a standoff distance. Autonomous after it has been dropped, it can be used at low altitudes, cross hilly terrain or veer sharply from the firing aircraft.

AASM INS/GPS IR

The inertial/GPS/IR kit adds an infrared imager for terminal guidance. With a simplified model of the scene around the target first being uploaded to the weapon, this imager allows the AASM to recalculate its trajectory during the last few seconds prior to impact, using image recognition algorithms. This allows the AASM to hit its target with the highest possible accuracy, even if GPS coordinates are incorrect, or the GPS signal is unavailable. This version is called the SBU-64 Hammer.

AASM INS/GPS Laser

The inertial/GPS/laser kit adds terminal laser guidance to engage agile, moving land or naval targets, illuminated by a ground or airborne laser designator. It will be deployed by French armed forces starting in 2012. This version is designated the SBU-54 Hammer (Smart Bomb Unit).

The laser terminal guidance version can be deployed to engage moving targets, while the infrared terminal guidance version minimises target coordinate errors.

The combat proven missile can operate in all weather conditions during the day and night. It has vertical strike capability and can support deep strikes, close air support, air interdiction, and SEAD-type or anti-ship combat missions.

The propulsion system is fitted at the rear of the missile and consists of a solid rocket motor and four winglets for flight control.
