Ugroza

Ugroza (Russian: Угроза, meaning "menace") is a precision-guided weapons system made in Russian Federation. It is an upgrade for standard Russian "dumb" rockets, including the S-5, S-8, and S-13 rockets.[1][2] The system upgrades the "dumb" rockets with laser guidance, very significantly increasing their accuracy. It requires a laser target designator, from either an airborne or land based source, to "paint" a target. Circular error probable (CEP) is about 0.8 to 1.8 m,[1] while maximum ranges of rockets varies from the rockets used 1.5–8 km.[1] Ugroza allows rockets to be ripple-fired up to 7 at a time.

The notable novelty is that the system does not use aerodynamic flight control (e.g. tail fins), but impulse steering with mini-thrusters.[1] It has been dubbed as the Russian concept of impulse corrections (RCIC).[1]

The concept has been demonstrated by Ametech (Russian: Аметех - Автоматизация и механизация технологий[2]) on 1999 MAKS airshow,[1] but it is not known if the system has been manufactured since, and in what numbers. The name Ugroza (sometimes transliterated Ugrosa), have been first used for the company's semi-active laser-guided projectile (SAL-GP) for the 122 mm BM-21 Grad series of multiple rocket launchers (it did not enter production and have been shelved[3] as of 2010).

Sources are not clear whether optical (TV) guidance can be used in place of laser guidance.

The designation of rockets upgraded with Ugroza are given the suffix "Kor"[1] (from Russian корректируемые, meaning "correctable"):
