The Su-9 Fishpot

The Su-9 Fishpot was a Soviet interceptor from the later 1950s until the late 1970s. It was superseded by the Su-15 Flagon and MiG-25 Foxbat. Often mistaken for MiG-21 because of the delta wing, it was in fact a much larger aircraft with greater range. It was the second Sukhoi fighter with the Su-9 numerical designation, the first being a prototype early twin engine early jet fighter similar to the Me-262 which never saw service. The Su-9 shared an airframe and engine with the Su-7 Fitter, developed somewhat in parallel. It only saw service with the Soviet Air Force (VVS) and was never exported.

As told by Yefim Gordon & Dmitriy Komissarov in their book Sukhoi Interceptors: The Su-9, Su-11, and Su-15: Unsung Soviet Cold War Heroes, the Su-9 achieved initial operational capability (IOC) in 1959, gradually replacing the subsonic, cannon-armed, MiG-17PF all-weather interceptor and the missile-toting supersonic MiG-19PM and by May 1960 the Fishpot-B was in service with the Soviet fighter arm of the air defence force (IA PVO).

A challenge for flight crews

The aircraft proved to be quite a challenge for flight crews: the Su-9 was famed for its ‘willingness to fly’, and the type’s service record includes a few truly amazing incidents. For instance, on Jun. 11, 1964 the crew of a 179th IAP (Fighter Aviation Regiment) Su-9U, trainee Capt. Mel’nikov and instructor Maj. Nikolayev, lost concentration during the approach to Stryy AB after a training sortie, allowing speed to bleed off dangerously, and ejected, fearing that the trainer would stall and spin. Left to its own devices, the aircraft unexpectedly righted itself, climbed to about 1,300 m (4,265 ft.), and circled around the airbase until it ran out of fuel. It then glided down and landed on its own (!) in a ploughed field; unfortunately the landing was far from perfect, and the aircraft sustained major structural damage, being declared a write-off.

Another case when the air craft displayed more presence of mind than the driver occurred just seven months later. On Jan. 25, 1965, Lt.-Col. Ovcharov, a 737th IAP pilot, took off from Sary-Shagan AB on a night training mission in a single-seat Su-9; soon afterward he discovered a control system malfunction and promptly ejected. Came dawn next day, and the aircraft was discovered 32 km (193/4 miles) from the base in virtually undamaged condition, save for a punctured no. 1 fuel tank! The aircraft was sitting ‘in the middle of nowhere’ in flat steppeland, resting on its drop tanks, which had been flattened on impact.

Investigation showed that the aircraft had not even used up the fuel completely, and it was sheer luck that there had been no fire. The pilotless Su-9 had touched down in a wings-level attitude at about 400 km/h (248 mph), the crushed drop tanks turning into improvised skis (!) on which it slithered for about 250 m (820 ft.) before coming to a standstill. The bottom line: this unique episode was classed as a ‘nonfatal accident / aircraft repairable’, and the Su-9 was actually repaired and returned to service!

Mindful of the Su-9 reliability issues, the pilots used to say: ‘Flying the Su-9 is like cuddling a tiger: it feels good but it is dangerous and the outcome is uncertain.’
