Re: Sukhoi Su-9
A more powerful [Vous devez être inscrit et connecté pour voir ce lien] was installed, providing 9.8 kN (2,210 lbf) more afterburning thrust for improved climb rate and high-altitude performance (and to compensate for increased weight).
The Su-11 can be distinguished from the Su-9 by the external fuel pipes atop the fuselage, aft of the cockpit.[Vous devez être inscrit et connecté pour voir ce lien]

The Su-9's beam-riding [Vous devez être inscrit et connecté pour voir ce lien] missiles were replaced by a pair of [Vous devez être inscrit et connecté pour voir ce lien] weapons, usually one R-98MR [Vous devez être inscrit et connecté pour voir ce lien] and one R-98MT [Vous devez être inscrit et connecté pour voir ce lien] guided.
Like many interceptors of the period, it had no cannon.[Vous devez être inscrit et connecté pour voir ce lien]
[Vous devez être inscrit et connecté pour voir ce lien]Production of the definitive Su-11-8M began in [Vous devez être inscrit et connecté pour voir ce lien], ended in [Vous devez être inscrit et connecté pour voir ce lien], after about 108 aircraft had been delivered, although it is believed that at least some Su-9s were upgraded to Su-11 form.[Vous devez être inscrit et connecté pour voir ce lien]

Re: Sukhoi Su-9
It was reported that a Su-9 was involved in the interception of [Vous devez être inscrit et connecté pour voir ce lien]' U-2 on Soviet territory on 1 May 1960.
A newly manufactured Su-9 which was in transit flight happened to be near Powers' U-2.
The Su-9 was unarmed and was directed to ram the U-2.
One ramming attempt was made and the Su-9 missed the U-2, primarily due to large difference in the speed of the two planes.
No further ramming attempt was made due to the Su-9's lack of fuel.

Development problems and accidents delayed squadron introduction with the [Vous devez être inscrit et connecté pour voir ce lien] / [Vous devez être inscrit et connecté pour voir ce lien] until [Vous devez être inscrit et connecté pour voir ce lien] and only small number of aircraft were delivered.[Vous devez être inscrit et connecté pour voir ce lien]
[Vous devez être inscrit et connecté pour voir ce lien]
Even with the superior radar, the Su-11 remained heavily dependent on [Vous devez être inscrit et connecté pour voir ce lien] (GCI) to vector its pilot onto targets.

Re: Sukhoi Su-9
It had no capability against low-flying aircraft either, and Sukhoi OKB
considered the Su-11 to be a misfire, much inferior to the far more
formidable [Vous devez être inscrit et connecté pour voir ce lien] ('Flagon').
Nevertheless a few examples remained operational until early 1980s.

Variants
T-3
(OKB-51 - Izdeliye 81) Pre-cursor prototype delta-winged interceptor fighter developed in parallel with the S-1 and S-2
swept-winged tactical fighter prototypes, flying for the first time on 26 April 1956.
S-3
Swept-winged interceptor fighter, cancelled when almost complete, in favour of the T-3.
PT-7
The second T-3 prototype was adapted to carry the K-7L or K-6V AAM's(Air to Air Missile) and a new radar with distinctive radome/shock cones on the upper and lower lips of the air intake which was angled back at 16O.
This aircraft was re-designated PT-7 (PT probably stood for Perkhvatchik Treugol'nym [krylom] – delta-winged interceptor).

PT-8
(Factory No.153 - Izdeliye 27) Intended as the production version of the T-3/PT-7, the PT-8 was ordered in small quantities from Factory No.153 before a new directive from the [Vous devez être inscrit et connecté pour voir ce lien] specified new performance parameters for the new interceptor.
Three aircraft were completed and delivered to OKB-51 by rail where only one flew.
T-39
To investigate thrust augmentation by injecting water into the afterburner, the third pre-production T-3, 'PT8-3', was modified as the T-39, with the rear fuselage fuel tank replaced by a water tank.
The T-39 never flew due to the water injection programme being transferred to the TsIAM (Tsentrahl'nyy Institoot Aviatsionnovo Motorostroyeniya - central institute of aviation motors).
The T-39 was later modified as the T-49.

T-43
The first real prototype of the Su-9 with the distinctive round intake with conical shock body/radome in the centre was the T-43-1.
The Sukhoi 9, its prototypes and immediate derivatives, were designated in-house, at OKB-51, as T-43's with a numerical suffix such as T-43-1 (first prototype) and T-43-7, a prototype used for autopilot development.
T-47
The T-47 was an experimental interceptor fitted with the 'Almaz' radar in an enlarged radome and di-electric panels either side of the nose.
Converted from the second PT8 airframe the T-47-1 first flew on 6 January 1958, but its test programme was curtailed to allow the engine to be fitted to the PT8-4.
The T-47 prototypes paved the way for the Su-11 production interceptor.

T-5
A powerplant test-bed converted from the T-3 prototype with two Tumansky R11F afterburning turbojets side by side a new rear fuselage from frame 28 rearwards. A new T-43 style nose with axi-symmetric air intake and shock body was also fitted.
The T-5 flew for the first time, after conversion, on 18 July 1958.
PT-95
The second pre-production T-3 (PT-8-2) never flew as a PT-8 but was immediately converted as a powerplant test-bed with specially instrumented engine and test equipment, as well as a T-43 nose.

L-43
A U-43 prototype was converted to become an ejection seat trials platform as the L-43 (a.k.a. Izdeliye 94).
U-43
The prototypes for the two seat Su-9U trainer were designated U-43.
