Kh-29 air-to-surface missile employed in unguided surface-to-surface role in Libya

In a series of photos coming out of Tripoli, Libya, militants are shown using sophisticated guided air-to-surface missiles as unguided surface-to-surface weapons. The missile shown, a Kh-29T, is believed to have been seized from a weapon depot close to Ghardabiya airbase, near Sirte.

The Soviet Kh-29 series of missiles (NATO reporting name AS-14 ‘Kedge’) began development in the 1970s, eventually entering service in 1980. Intended for use on larger targets that lighter missiles like the Kh-23 and Kh-25 were inadequate for, Kh-29 series missiles soon became standard armaments on almost all Soviet and Russian strike planes and multirole fighters. This includes the Su-17M4, MiG-27K, Su-24M, Su-25, Mig-29M, and others.

Featuring a 320 kg high explosive (HE) warhead, Kh-29 missiles are fitted with an impact target sensor, allowing penetration of the exterior of the target prior to detonation. Separated into 5 main sections, the front “seeker” component (see section marked “I” in technical drawing below) has two main guidance variants, with the Kh-29L using semi-active laser guidance, and the Kh-29T and Kh-29TE using passive TV guidance. The Kh-29T has an optimal target detection range of 4 – 5 km and, with ideal weather conditions, is highly accurate, with a 2.2 m circular error probable (CEP).

In Libyan service, the Kh-29T is believed to have been solely used on the Su-24 aircraft delivered from the Soviet Union in the late 1980s. Unable to maintain their five Su-24MKs and one Su-24MR internally, due to an imposed arms embargo, Libya turned to both Syria and Iran for assistance in keeping the fleet operational. Syria was subsequently repaid with one Su-24MK fighter-bomber and Libya’s sole Su-24MR reconnaissance aircraft. After losing their four remaining Su-24MKs – one during operations early in the Libyan conflict, and 3 to NATO air strikes at Ghardabiya airbase – it appears there are no remaining aircraft in the Libyan inventory capable of carrying some of the extant air-to-surface weaponry, including the Kh-29T.

It now seems efforts have been undertaken to press some of these munitions into service again, albeit in an improvised ground-to-ground role. The Kh-29T shown in the pictures above appears to have modified fins, presumably intended to provide a more stable flight path in this new unguided capacity. The large size of the warhead is assumed to be the reason these missiles were chosen.
