Russian source reports PAK DA is developed by Sukhoi, 120 t class, and will be equipped with 4 Al-41 engines. It means Sukhoi has finally won competition with Tupolev for PAK DA program. The new prospective bomber will have the same range like Tu-160 (14+ thousand kms) and will gradually replace Tu-95 (60+ units), Tu-160 (15 units) and partially Tu-22M3. The technical-economic reasons played important role in the decision, the better shape of Sukhoi design house too. To make an adequate replacement for such high number of planes by Tu-160 size bombers (a new kind or refurbished) is impossible, they said.
