Artillery Round with Terminal Phase Trajectory Correction

Techmash Concern – a Rostec company – is developing a new concept for guided artillery munitions. The key feature of the round is trajectory correction in the terminal phase of flight: moving in conventional ballistic manner on firing, but using an onboard control system to correct its trajectory in the vicinity of the target.

“It is a new 152mm correctable projectile for artillery of that calibre. It is difficult to build a control system into ammunition of this type, due to the high dynamic loads that the projectile undergoes at the moment of firing, while it is spinning within the barrel bore and during the flight. At a spin rate as high as 30,000 revolutions per second, optics do not work — the picture is blurred. We are considering several ways to correct the projectile trajectory in the final stage, including aerodynamic surfaces on the fuse and mini jet engines,” commented Techmash Deputy CEO, Alexander Kochkin.

Detailed specifications and the general outline of the as-yet-unnamed new projectile are now under development. The likely price point for the new projectile will place it in the mid-range, the company claims – cheaper than guided projectiles such as the KRASNOPOL, but more expensive than conventional projectiles.

“Rostec pays special attention to developing and producing high-tech products and promoting them on the international market. I am sure the new correctable projectiles that are being developed by Techmash will interest our foreign partners in a number of countries, including the Middle East,” explained the Industrial Director of Rostec’s conventional weapons, ammunition and special chemistry cluster, Sergey Abramov.

Rostec is conducting a large-scale Armament Cluster Development programme, with an approved strategy targeting 17% annual revenue growth in rubles by 2025, while improving operational efficiency and entering the global market.
