Analyzing the experience of operation in combat units and combat experience of the application of SB bomber (IPG-40), Chief Designer AA. Archangel scheduled the radical modernization of its, which was to take place in two stages: in a first step by improving aerodynamics, and the second - through the creation on the basis of Security Council, essentially, new aircraft with a maximum speed 600 kmh. The decision released by AA. Archangel required to build two prototypes: one with engines M-105, other motors M-104.

The first aircraft with engines M-105, MCM symbol with 2M-105 (minor modification of the "H" Aircraft), It was built in May 1939 g. The main differences were as follows: new engines M-105, wing area is reduced by 8 m2, forward fuselage shaped streamlined shape, consoles installed additional fuel tanks, from the navigator has a second control. Despite the increase in horizontal flight speed in comparison with serial aircraft SB, state tests aircraft could not resist. The main reason was that, that located in the bow defense installation had insufficient firing angle, and the machine-gun slit deteriorating conditions of work of the navigator. The absence of the hatch defensive installation did lower hemisphere completely defenseless. Despite the bad bringing engines M-105, they were installed in the serial SB.

The next brainchild AA. Arkhangelsk was the SB-RC plane (Ar-2), Further modification of the Security Council. On one of the mass-produced cars with engines M-105 were established water radiators in special channels inside the wing. In the end of April 1940 g. Test Pilot MA. Lipkin tested the first SB-RK. Tests have shown a significant improvement in the flight data, speed increased to 492 kmh. On brake and automatic output lattice plane of a dive it was first mounted second instance Sa-RK. On standard SC-RK replaced by a nose on an improved aerodynamic respect, as well as the reduced height new hood canopy radio operator-gunner. Defensive armament consisted of three machine guns Aircraft ShKAS. Bomber arms compared with serial SB had a number of improvements, in particular, It has increased the possibility of the suspension of larger bombs. During the test was performed 25 dives at an angle of 40 ° to 75 °.

According to the results of the state tests, it was concluded: SB-RC plane (at 1940 g. he was awarded the designation of Al-2) According to their letnotehnicheskim much better serial SB. But at the same time from the AA. Arkhangelsk and plant number 22 required to bring to mind Propeller engines. In total, it was released about 200 Car rear-2. By order of the Defense Committee of the 11 February 1941 g. The serial production of Ar-2 was discontinued in favor of the launch of a series of dive bombers Pe-2. As of 1 June 1941 city, in Air Force units’ there were only 164 Ar-2 aircraft.
In the context of the retreat of the Red Army and was a poor organization Ar-2 bombers could not demonstrate this all the, what they were able to. By the end 1941 g. it was lost 95 Ar-2 aircraft. calculations show, that under typical conditions of fighting on the Eastern Front, at the decision of the combat mission the destruction of small trudnouyazvimyh purposes, Ar-2 bomber is superior to BB-2PB bomber almost 5,5 fold, a Pe-2 - in 1,4 fold. When solving a combat mission to destroy poorly protected targets of all serial Soviet bombers best result showed again Ar-2. the main thing, Ar-2 had excellent runways quality and was more accessible, than the Pe-2, for the development of young pilots.
