Description
Following the underwhelming engine performance of the "Aircraft K" (Su-9) project using reverse engineered German Jumo-004 engines, the indigenous Lyulka TR-1 engines originally intended were finally completed. However, it was quickly discovered that these massive engines would require a complete redesign of the engine pods and wings to be mounted, and the tailplane changed slightly to move the elevators out of the engine's wash. As a result, the aircraft with the new wings and engines looked substantially different, even from afar. This directly resulted in it receiving new designations, first "Aircraft KM" and later redesignated into Su-11. There was also a second parallel project, "Aircraft KT" (Su-13) which would have had the Toryi (Thorium) radar from the La-200 in the nose. The Su-11 first flew on May 28th, 1947, and had a maximum speed of 940 km/h at sea level, but as flight testing quickly revealed, the aircraft had horrible longitudinal stability at high speeds. The engineers were unable to revise the airframe further to fix these stability issues, and coupled with the lack of available new Lyulka TR-1 engines, in 1948 the program was cancelled altogether, with only one Su-9, one Su-11, and no Su-13s built. Instead, the Soviet Government favoured the Mikoyan I-310 prototype (which also first flew in 1947), using the more readily available Klimov RD-45 (reverse-engineered Rolls-Royce Nene) in a more stable and reliable airframe, which ultimately became the MiG-15.
The Su-11 was introduced in Update "Ixwa Strike" as a GE 
premium aircraft in the Soviet tech tree. Bearing a lot of resemblance to its tech tree brother, the Su-9, the Su-11 in reality is a completely different beast. The upgraded engines and wing shape give the Su-11 unparalleled acceleration and high-speed performance compared to its adversaries at this battle rating. All in all, the Su-11 is a very powerful premium aircraft and a decent pick for people looking for something to research the early Soviet jet aircraft ranks with.

Armaments
Offensive armament
The Su-11 is armed with:
- 1 x 37 mm N-37 cannon, nose-mounted (40 rpg)
- 2 x 23 mm NS-23 cannons, nose-mounted (100 rpg = 200 total)
Suspended armament
The Su-11 can be outfitted with the following ordnance:
- Without load
- 1 x 250 kg FAB-250M-46 bomb (250 kg total)
- 2 x 250 kg FAB-250M-46 bombs (500 kg total)
- 1 x 500 kg FAB-500M-46 bomb (500 kg total)
Usage in battles
The Su-11 can easily be one of the best aircraft at its battle rating. Its primary strength is the excellent acceleration, compared to contemporary jets. It has excellent energy retention (ER) and average to good manoeuvring energy retention (MER).
In general, the best tactic with the Su-11 is to play to its strengths, as with any vehicle; In the Su-11's case, particularly its acceleration and ER can be exploited. Take off from the airfield, and level out quickly. Don't bother gaining initial altitude, jet engines particularly early jet engines, accelerate better at sea level. Turn at least 30 degrees away from the center of the map, and build up speed. It is recommended to build up to about 725 km/h - 805 km/h (450 mph to 500 mph), then place the aircraft into a 20-30 degree zoom climb (steady-state climbing is possible in this aircraft, but like most early jets, zoom climbing is most efficient).
This will take the Su-11 well above 3.5 km, usually closer to 5 km. Dive on unsuspecting enemies, particularly aircraft that don't manoeuvre well, and once they are destroyed, begin a 20-30 degree zoom climb to regain your lost altitude. The energy retention is excellent, and you can typically regain all your lost altitude, if not gain on top of it. Usually enemies on the Su-11 tail can be out-accelerated, which causes most players to lose interest in engaging and break off the chase, even if their aircraft's top speed is higher than the Su-11.
Manoeuvrability is average, but certainly not poor. The Su-11's manoeuvring energy retention is excellent, If forced to dogfight and the opponent vehicle has similar manoeuvrability, simply drain them of their energy with long, sweeping movements.
While the Su-11's armament packs a punch, excellent marksmanship is an absolute necessity, given the low ammo pool of only 200 23 mm rounds and 40 37 mm rounds. In addition it has a relatively low rate of fire (on both cannons). The rounds are also relatively low velocity (especially the 37 mm round). However, the rounds are extremely powerful, with the 37 mm round able to destroy heavy bombers with a couple of well placed hits, and the 23 mm round able to destroy lighter aircraft with 1-2 hits. The best option is to get as close as possible before opening fire to ensure that the enemy plane gets knocked out.
Pros and cons
Pros:
- Decent manoeuvrability
- Good acceleration for an early jet
- Fast aircraft
- Heavy armament
- Excellent energy retention
Cons:
- Engines overheat quickly at 100% power
- Low ammo pool
- Low rate of fire, relatively low velocity (particularly the 37 mm) cannons
History
The Su-9 was an early Soviet jet fighter built using knowledge and parts derived from the German Me 262 jet fighter.
The Su-11 was a project in 1946 to mount Yakovlev versions of the RD-10F engines in the Su-9 jet fighter. After testing the Su-9 in the wind tunnel, it was found that engines mounted in the wings rather than underneath reduced drag and that the wingtips also needed a redesign. As such, the Su-11 received a completely redesigned wing and before completion it was also received the Lyulka TR-1 turbojet engines. The two engines produced 2,865 lbf of thrust each for 5930 lbf of thrust total.
The Su-11 first flew on 28 May 1947, demonstrating a maximum speed of 940 km/h at sea level. Unfortunately, the design had a bad longitudinal stability and even modifications to the wing engine nacelles did not solve the issue. Because of these issues, the Su-11 programme was cancelled and did not enter production.
