Krasnopol (weapon system)

The 2K25 Krasnopol is a Soviet 152/155 mm cannon-launched, fin-stabilized, base bleed-assisted, semi-automatic laser-guided artillery weapon system. It automatically 'homes' on a point illuminated by a laser designator, typically operated by a drone or ground-based artillery observer. Krasnopol projectiles are fired mainly from Soviet self-propelled howitzers such as the 2S3 Akatsiya and 2S19 Msta-S and are intended to engage small ground targets such as tanks, other direct fire weapons, strong-points, or other significant point targets visible to the observer. It can be used against both stationary and moving targets (providing these remain within the observer's field of view).

The weapon system was developed in the Tula-based KBP Instrument Design Bureau under the supervision of A. G. Shipunov [ru]. Work on the project was initiated in the 1970s. In February 1986 the Krasnopol system was adopted by the Soviet Army under the designation 3OF39, and began mass production in Izhmash and Izhmeh factories. Since 2002, it is augmented by the 120- and 122 mm Kitolov-2 laser-guided system.

A 155 mm variant of the project was also developed to access the commercial markets, which can be fired from howitzers such as the G6 and M109A6. Besides Russia, the Krasnopol is also manufactured by Chinese defence industry conglomerate Norinco.

On July 28, 2022, Russian news agency TASS reported that Kalashnikov Group is working on an modernization of Krasnopol with increased range, better at striking small-size targets, enhanced warhead and raised efficiency during clouds and strong wind.

In early 2023, it was reported that Russia had increased the production of Krasnopol "several times" for the needs of the war in Ukraine.

The development and trial use of a drone-carried version was reportedly completed as of May 22, 2023. Supplies of a modernized version began in August 2023 and its application in November 2023.

The 2K25 Krasnopol system consists of the 3OF39 precision shell, a 1D22, 1D20, or 1D15 laser target designator (LTD), and the 1A35 shot synchronization system. The laser designation system has a range of 5 kilometres (3.1 mi), while the projectile itself has a range of 20 kilometres (12 mi) and a target seeker radius of 1 kilometre (0.62 mi). The two-part projectile is divided into the following sections: target seeker, guidance module, warhead and rear compartment. The seeker and guidance module are stored as a single component in sealed container, as is the rear section with warhead; this allows the oversized projectile to be loaded and transported inside existing ammunition containers in legacy self-propelled howitzers. The two components are joined immediately prior to firing.

The system functions as follows. The observer determines the target location (e.g. map coordinates or bearing and distance from their own position), ensures that their laser target designator can 'mark' the target and requests or orders a fire mission against the target using Krasnopol. A gun is then aimed at the target location and a guided shell is fired. The firing unit uses their 1A35K command device to send a signal via a communications link confirming the firing of the projectile to the 1A35I observation post device with the observer. The laser target designator is then used to illuminate the target and the in-flight projectile detects the radiant laser energy reflected by the target and the navigation system steers the shell towards the point of greatest incident energy—the designated target with top attack pattern. The iris of the optical seeker head is protected by a cap which is ejected by a mechanical timer upon firing. The guidance module contains an inertial reference system, a power source, various electric motors and controls and four folding wings used to execute command guidance signals. The warhead is a high explosive fragmentation type which can also be used against heavily armored vehicles such as tanks owing to the steep trajectory of the projectile which allows it to defeat the relatively thin roof armor on most vehicles. Behind the warhead is a rear compartment which houses four folding stabilizers. Krasnopol system can also fire a salvo from multiple artillery pieces on one target using a single laser designator.
