Features of the design and use of winged guided bombs GLSDB
GLSDB is a planning aviation a bomb crossed with a solid-propellant jet engine from the M1990 missile developed in the early 26s, used in the HIMARS MLRS systems. Unguided missiles of this class are obsolete, but instead of disposing of them, it was decided to cross them with the GBU-2000 guided bombs developed in the early 39s.
With the help of a rocket engine, a bomb launched from the HIMARS MLRS systems accelerates to a speed of 900-1200 m / s, after which, when it reaches a height of about 15-25 thousand meters, it undocks from the upper stage and begins controlled planning towards the target. The bomb is equipped with guide flaps, aerodynamic rudders, and a GPS module. The projectile has a small size, making it difficult to detect and defeat air defense systems.
The mass of the GBU-39 bomb without a jet engine is 134 kg. The mass of the warhead is 16 kg. When diving at a target from a great height, thanks to the tungsten tip, it is able to break through concrete shelters. The American corporation Boeing, the Swedish SAAB and the Norwegian NOBLE took part in the development of this ammunition.
Unlike conventional artillery systems, the GLSDB is capable of reaching 360-degree coverage at high and low angles of attack, circumnavigating terrain and hitting mountainous targets, and returning to a target behind a detached upper stage.
The declared target range of the GLSDB is 150 km. True, so far there is no evidence that in the ground version this ammunition hit a target at a distance exceeding 119 km. The estimated cost of such ammunition is 40 thousand US dollars, excluding the cost of the rocket engine and assembly work.
