Krasnopol (weapon)

The 2K25 Krasnopol is a Russian 152 mm cannon-launched, fin-stabilized, base bleed-assisted, semi-automatic laser-guided, explosive projectile. It automatically 'homes' on a point illuminated by a laser designator, typically operated by a ground-based artillery observer. It is fired mainly from Russian self-propelled howitzers such as the 2S3 Akatsiya and 2S19 Msta-S and 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).

Development
The weapon system was developed in the Tula-based KBP Instrument Design Bureau under the supervision of A.G. Shipunov. Work on the project was initiated in the 1970s. In February 1986 the Krasnopol system was adopted by the Soviet Army under the designation 30F39, 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 Krasnpol is also manufactured by Chinese defense industry conglomerate Norinco.

Description
The 2K25 Krasnopol system consists of the 30F39 guided 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 km, while the projectile itself has a range of 20 km and a target seeker radius of 1 km. 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 shell detects the radiant laser energy reflected by the target and guides itself towards point of greatest incident energy—the designated target. 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 and inertial reference system, a power source, various electric motors and controls and four folding canards 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.

After destruction of the initial target, the LTD operator may request or order another target. If these subsequent targets are close together they should be upwind (from the previous target) to reduce smoke and dust interference with the designator.

Krasnopol is capable of hitting targets moving at speeds up to 36 km/h.

Variants
The original model of the Krasnopol was designed to be used with former Soviet-Bloc artillery systems of 152 mm, such as D-20, 2S3 Akatsiya, 2A65 (Msta-B). Krasnopol carries a 20.5 kg high explosive fragmentation warhead. The entire missile weighs 50 kg. However, its length made it incompatible with the autoloader of the 2S19 152mm Self-Propelled Gun.
 * 2K25 Krasnopol

The Krasnopol-M was a miniaturized version of the projectile, developed in the mid-1990s by Shipunov's team at the KBP Design Bureau taking advantage of new electronics technology acquired in the design of the 120 mm Kitolov-2 guided projectile (similar in construction and purpose; this is in essence a smaller model of the Krasnopol to be used with the 2S9 NONA 120 mm mortar and designated 30F69 and a related projectile for 122 mm howitzers designated Kitolov-2M 30F69M) was made with a shorter length to enable it to be used with autoloader-equipped self-propelled guns without having to be disassembled into two parts. It also comes in an alternate 155 mm caliber to allow it to be used with NATO-standard 155 mm howitzers. Besides the reduced total length, the Krasnopol-M also has a different protective cap for the optical seeker.

The Krasnopol-M2, a further development based on Krasnopol-M, is a 155mm artillery projectile designed to engage armored targets. It uses a semi-active laser (SAL) guidance system in the terminal phase of its trajectory.
