These views of the MiG-15bis (ISh) in happier times when it was safely tucked away in a hangar show the triple-tandem weapons racks on each mega-pylon; these could be angled down 15 degrees, allowing six FFAR pods to fire at once when the aircraft was in level flight. Note also how the top of the pylon passes over the top of the wing.
After World War II was over, the leaders of the USSR realized that they were behind the leading states of the world in the sphere of jet aircraft construction, most notably in the full-scale production of turbojet engines. Consequently, a delegation including the designers A. I. Mikoyan and V. Y. Klimov was sent to Great Britain towards the end of 1946. Their negotiations were successful, resulting in the purchase of two of the most advanced turbojet engines at that time: the Rolls-Royce Derwent Mk.V and the Rolls-Royce Nene I/Nene II. The British consented to sell their newest strategic designs easily enough, since they believed that the Soviet industrial/technological apparatus could not handle the mass production of sophisticated assemblies. However, very soon that the Rolls-Royce engines were launched into full-scale Soviet production under the designations RD-500 and RD-45.
The emergence of the new engines led to the creation of Soviet jet fighters able to compete with the leading models of the world. In 1947, the Mikoyan Design Bureau started the development of a front line fighter with a Nene (RD-45) turbojet engine and an airtight cockpit: the I-310 (“”S””). The first S-01 prototype aircraft made its first flight on December 30, 1947, and, after working on the test results, was launched into full-scale production in 1948 under the designation MiG-15. The plane’s airframe was an all-metal monoplane configuration with mid-swept wings and empennage. Thus the MiG-15 became the first production swept-wing fighter.
The MiG-15 was equipped with a RD-45F single-shaft turbojet engine rated at 2,270 kg of thrust with a double-entry centrifugal compressor. The plane’s armament included a 37mm Nudelman N-37D cannon with 40 rounds and two 23mm Nudelman-Suranov NS-23KM guns with 160 rounds in total. The cannons were mounted in the forward fuselage on a lowerable carriage. Two 100-kg or 50-kg bombs could be suspended under the wings. To increase its flight range, the aircraft could carry two external fuel tanks with a capacity ranging from 250 to 600 liters.
The MiG-15 fighter was notable for its simple and reliable structure, high flight and operating characteristics, and powerful armament. Its maximum speed, rate of climb, ceiling, and flight range were the best among Soviet fighters at the time and superior to many foreign aircraft, as well.
The first production MiG-15s with RD-45F engines began to leave the factory floor in early 1949. In 1950, more advanced MiG-15bis fighters replaced them in the factory assembly lines
A fighter-bomber conversion of the MiG-15bis, designated ISh (Istrebitel-Shturmovik).
One of the most distinctive trials modifications was the “MiG-15bis-ISh” ground-attack aircraft, which featured a modified wing sporting large “beams” that were used to carry ordnance. About twelve were built, but since the rival Sukhoi OKB was developing dedicated ground attack aircraft at the time, the MiG concept went no further.
In an attempt to enhance the combat potential of the MiG-15bis, the Air Force’s Aircraft Operations and Repair Research Institute developed a specialized attack version from 1958 to 1964. The aircraft was designated MiG-15bis (ISh), the suffix standing for istrebitel’-shtoor- movik (fighter/ attack aircraft).
The MiG-15bis had reinforced wing spars and huge weapons pylons extending far beyond the wing leading edge, about halfway between the main gear units and the drop tank attachment points. These were fitted with triple weapons racks located in line, permitting the carriage of three 50- to 100-kg bombs, FFAR pods, or heavy unguided rockets under each wing.
An experimental batch of 12 air- craft was built; some sources, though, quote a much lower figure (three flying prototypes and a static test airframe). One of them survives at the Russian Air Force Museum in Monino, east of Moscow.
The MiG-15bis ISh is outfitted with the following offensive weapons:
1 x 37 mm N-37D cannon with 40 RPG.
2 x 23 mm NS-23 cannons with 80 RPG (160 total rounds)
The MiG 15 bis IShs carries multiple offensive weapons which consist of two 20 mm cannons and a 37 mm cannon. There is limited ammo on both, so eliminate enemies on the first pass if possible.
The MiG-15bis ISh can be outfitted with the following ordnance:
6 x 100 kg OFAB-100 bombs (600 kg total)
4 x 250 kg OFAB-250-270 bombs (1,000 kg total)
2 x 500 kg FAB-500M-54 bombs (1,000 kg total)
8 x S-1of rockets
48 x S-5K rockets
48 x S-5M rockets
The MiG benefits from multiple mounted weapons, consisting of six x 100 kg bombs, four x 250 kg bombs, two x 500 kg bombs or 8 x S-1 or 48 x S-5K/S-5M rockets, mounted inside two external mounted pods. Note that the pods are mounted at a downward-facing angle. This aircraft carries no air-to-air weapons nor any type of decoy munitions.
