Lockheed Martin Corp. It is developing a long-range, high-precision air-to-ground cruise missile capable of destroying key enemy targets at a range of up to 1,930 km. The JASSM missile, which has been in service since 2009, is a long-range, high-precision, air-to-surface missile. It is used to destroy well-protected, fixed and moving targets. According to Building-tech.org, JASSM has a flight range of 370 km, while the extended range JASSM-ER has a flight range of 980 km.
The design of the cruise missile has an aerodynamic scheme and is a low-flying aircraft with the formed aerodynamic surface (wings and keel). Carbon fiber-based composite materials were widely used in the rocket design, and the body of the rocket was made entirely of carbon fiber. As a power plant, Teledyne CAE’s single-stroke, single-circuit J402-CA-100 turbojet engine is used, with an improved compressor and fuel system compared to the original J402-CA-400 engine of the Harpoon anti-ship missile.
The control system is inertly combined with the correction of the error accumulated according to the data of the NAVSTAR satellite navigation system signal receiver, the infrared homing head (IR homing head) and the autonomous target recognition software and hardware are finally used. section of the flight path.
The JASSM-ER (AGM-158B) modification differs from the basic version of the missile with increased fuel tanks and a more economical two-circuit Williams International F-107-WR-105 turbojet engine. With these improvements and a longer mid-altitude range, the JASSM-ER can hit targets up to 980 km from the launch site.
Engineers plan to double the flight range of the JASSM-ER (AGM-158D) to 1,930 km and equip it with a 907 kg high-explosive warhead. To do this, the developers will improve the design of the wing, install a new, more advanced missile control unit, apply an innovative paint coating and integrate a more powerful GPS signal receiver.
The JASSM-ER cruise missile uses precision steering and steering, which allows it to accurately hit the target even in adverse weather conditions, day or night. The missile is equipped with an infrared homing head, a GPS navigation system with protection against obstacles created by the enemy’s EW devices.
