According to Russia’s deputy defense minister Yuri Borisov—as cited by TASS—the Tu-160M2 has been fundamentally upgraded with completely new mission systems and other improvements over the existing M variant. “This will be essentially a new airplane, not a Tu-160 but a Tu-160M2,” Borisov told RIA Novosti last year [5].
Details on the exact nature of the Tu-160M2 upgrades are scarce. Presumably, Tupolev has made long-overdue adjustments to the airframe that were supposed to have been implemented during the Blackjack’s original production run. However, those tweaks are likely to be fairly minor. The major upgrades are almost certainly going to be focused on the bomber’s avionics suite.
Russia’s Radio-Electronic Technologies Concern (KRET) is working on developing the new avionics suite for the Tu-160M2. “Today we can say with confidence that the new aircraft will be constructed using the elements of integrated modular avionics (IMA),” the company told Russia’s state-owned RIA Novosti. [6] “In the project to modernize the Tu-160, KRET will be creating new on-board systems, controls, a gimbal-less inertial navigation system, electronic warfare complex, fuel use monitoring systems, as well as weapons control systems.”
