OFAB-100 is the collective name of the Soviet, and now Russian, air fragmentation bombs from the Cold War and modern times. The OFAB-100-120 bomb is 105 cm long with a diameter of 27.3 centimeters. Its total weight, in turn, is 123 kg, with the explosive mass slightly exceeding 42 kg. The bombs of this family were designed primarily to destroy the enemy's manpower, but also permanent points of resistance - including those strongly fortified. Bombs can be dropped from a height of 5,000 to 15,000 meters, with the carrier's aircraft speed not exceeding 1,150 km / h. It is assumed that the explosives of these bombs are mainly TNT, but they probably also use other explosives. Bombs of this type can be carried by such planes as, for example: Su-17, Su-25 or Su-30. They were used in combat, inter alia, during the war in Afghanistan (1979-1989).
The Sukhoi SU-27 (NATO: Flankier) is a Soviet, twin-engine heavy interceptor designed to gain air supremacy. The prototype flight took place in May 1977. The SU-27 aircraft was developed as a response to the introduction of the F-15 Eagle into service in the USAF. The SU-27 is a very successful design. Much of its fame is due to the wonderful Saturn-Liulka AŁ-31F engines, which deliver 12500kg thrust with afterburners turned on, while being easy to service and interchangeable right and left and vice versa. In addition, unlike many previous Soviet designs, the SU-27 are characterized by a long service life of up to 3,000 hours when checked every 100 hours. This machine is at least comparable with the corresponding versions of the F-15 or PANAVIA Tornado ADV. The SU-27 is usually armed with short-range AA-73 Archer and long-range R-27 rockets, as well as the 30mm GSh-30-1 cannon used in the MIG 29. Its advantages are high accuracy and rate of fire (1500 rounds per minute), its disadvantage is the short life of the drum, which must be replaced after 80 seconds of shooting! The standard SU-27 radar is the RŁPK-27 device. The SU-27, together with the MIG 29 aircraft, are the basic fighters of the Russian Federation's air force. To date, a dozen or so versions of this aircraft have been created. Noteworthy are, among others: SU-27, marked as SU-27S, i.e. the basic hunting version, and SU-27SK, i.e. the export version. Technical data (SU-27S version): length: 21.9m, wingspan: 14.7m, height: 5.92m, maximum speed: 2.35Ma, rate of climb: 300m / s, practical ceiling: 19000m, maximum range: 3530 km, armament: fixed - one 30mm GSh-30-1 cannon, suspended - up to 8000 kg of cargo.
