KAB-250 Guided Bomb

In 2011, at the MAKS-2011 manufacturer of ammunition SSPE "Region" presented its latest development - aerial bomb KAB-250. Its characteristics were not disclosed. However, a number of features can be assumed that it is designed primarily for prospective fifth-generation fighter Sukhoi T-50. From which it followed that these weapons will have a qualitatively new intelligence.

There are two versions of the 250-kilogram KAB: a laser-guided version and a satellite-guided version. The KAB-250 follows the larger KAB-500, which made its combat debut in September 2015 when the Russian military began launching airstrikes in Syria. It can be mounted externally or stored in the jets internal weapons bays.

The KAB-250 weighs a total of 565 pounds, with a warhead of 365 pounds and a 200-pound explosive. The bomb is 10.5 feet long. It has a complex, compact tail design and is fitted with four long-chord, short-span wings to increase its glide range. It falls from an aircraft at a rate of 655-1,150 feet per second.

The 250 kg bomb is initially controlled by an inertial guidance system, which directs the bomb towards the target area. After reaching within two to three km from the target, the bomb's onboard computer activates the thermal homing device, which then acquires the designated target and then compares the image with the reference picture to adjust its precision-path, so that it falls within three-meter radius of the hit-zone.

The KAB-250 has a fragmentation warhead designed to destroy lightly vulnerable materiel, thin-skinned vehicles, and other enemy installations. The bomb can be dropped individually or in salvoes. The aircraft carrying the KAB-250LG-Es must be fitted with a laser illumination system or the target can be illuminated by a forward air controller.

The Russian arms manufacturers FSUE Region, at the Moscow Air Show in August 2003, featured a new LGB-250 laser-guided bombs. The guided bomb design, with the company's earlier models -- KAB-500 and KAB-1500 laser-guided bomb is completely different, but with the United States "Paveway II" laser-guided bombs similar. LGB-250 bombs of 100 kg warhead blasting anti-type, precision bombing from 3 to 10 meters. LGB-250 guided bombs are self-financing development projects, the development time of about one year, and is still being developed. The company hopes LGB-250 laser-guided bombs can be served in the end of 2003, equipped with Su-27 and Su-30 multirole fighter, used in conjunction with ground illumination.

The latest version of Russia's KAB-250 precision-guided bomb will soon complete trials, according to the weapon's manufacturer, Moscow-based Region Scientific & Production Enterprise JSC. "The bomb is in trials on the Sukhoi Su-34 [Russian fighter jet], with the trials to be completed late this year," Region's director general, Igor Krylov, told IHS Jane's at the Russian Defense Ministry Innovation Day.

The KAB-250 entered the weapons suite of the PAK FA fifth-generation fighter in 2016. According to Krylov, the KAB-250 was developed in response to the Small Diameter Bomb, which the United States developed for its F-22 Raptor and F-35 Lightning II fifth-generation fighters, IHS Jane's reports.

Igor Krylov, director general of Region JSC (a subsidiary of Tactical Missiles Corporation, KTRV), told IHS Jane's at the Russian Defence Ministry Innovation Day 2015. that there are two versions of the 250 kg Korrektiruyemaya Aviatsionnaya Bomba (KAB): a laser-guided version (the KAB-250LG-E) and the GLONASS/INS-guided KAB-250S-E. Its circular error probable (CEP) for ground targets is 3-5 meters.

According to Krylov, the KAB-250 was developed in response to the development of the Small Diameter Bomb (SDB) by the United States to equip its F-22 Raptor and F-35 Lightning II fifth-generation fighters.

Russias smart weapon inventory used in Syria in 2015-206 was a choice of time-proven bombs and missiles equipped with state-of-the-art system guidance. Precision weapons are used from high altitudes to exclude encounters with portable air-defense systems. A trusty weapon in the surgical strikes being carried out in Syria is the KAB guided bomb, which has two variants: KAB-250 and KAB-500. The KAB-250 guided bomb was developed in the 2000s specifically for the 5G PAK-FA fighter jet, where it is mounted in inside bays, which explains its distinctive egg-shaped form. The bomb can also be used by other modern Russian fighter jets, such as the Sukhoi Su-34 bomber, which drops these weapons on Islamic State targets in Syria from an altitude of 5,000 meters.

Work to create an updated KAB-250 air bomb is planned to be completed by the end 2017. This was announced on 20 July 2017 by the general director of the Tactical Missile Armament Corporation (KTRV) Boris Obnosov. "The presented corrected air bomb KAB-250 with a laser homing head ... I expect that by the end of the year we will finish work on this product," he said at the MAKS-2017 airshow. A guided ["corrected'] bomb with a laser homing head and high-explosive fragmentation warhead, KAB-250 is designed to destroy various equipment, fortifications, warehouses, infrastructure elements and other enemy objects. By using a laser guidance system, the bomb has a high hit accuracy.
