History:

The original , THE ANT-46 (DI-8) was designed so that its main armament were two bezzákluzové cannons APK-4 designer L. In. Kucharevkého, their development was stopped and how then in this country was a good habit - the designer was arrested.
ANT-46 stayed here ready for the state tests, but were not the weapons which he carried. On the basis of the recommendations of the first deputy chief designer of the CAGE . M. Petljakova was a prototype in the original design sent to larger adjustments in the production of factory no. 22.

Replaced was the wing, the prototype got rid of the wings originally designed for the SB-2, the engines were replaced with more powerful engines of domestic production and this type of AM-34FRN (reduktorový, turbocharged engine with increased performance), the engines were the work of a designer And. And. Mikulina. Another modification undergone tail surfaces, here has changed the shape and especially the swelled area. Not to forget just on the armament, which was the initial causal all the adjustments made, were submitted two proposals in the first draft was calculated with the four cannons ŠVAK in the wings, the second proposal was more sophisticated, cannons should be installed in easily removable battery under the fuselage. In the battery should be installed a total of five cannons ŠVAK including their containers, this vyzbrojní variant promised their easy maintenance and recharging of ammunition. Failed to authenticate me what výzrojí, the prototype was equipped with.

The modified aircraft was designated as the DI-8bis, but in the program of state testing was not included, he remained standing in the premises of the production plant no 22 no hope for the continuation of the test flights, it did so because of political pressures and intrikářství, which apparently stood M. M. Kaganovich, the official reason was the decision not to expand the number of existing types of aircraft.
