The Air Force is now testing new, high-tech sensors, software, electronics and other enemy radar-evading upgrades for its B-2 stealth bombers that are designed to preserve its stealth advantages and allow the aircraft to operate more effectively against increasingly capable modern air defenses.
The massive upgrade, designed to improve what’s called the bomber’s Defensive Management System, is described by Air Force developers as “the most extensive modification effort that the B-2 has attempted.”
The Defensive Management System is a technology designed to help the B-2 recognize and elude enemy air defenses, by using various antennas, receivers and display processors to detect signals or “signatures” emitting from ground-based anti-aircraft weapons, Air Force Spokesman Capt. Michael Hertzog said in a written statement.
The modernized system, called a B-2 DMS-M unit, consists of a replacement of legacy DMS subsystems so that the aircraft can be effective against the newest and most lethal enemy air defenses.
“This system picks up where mission planning ends by integrating a suite of antennas, receivers, and displays that provide real-time situational awareness to the aircrew. The DMS-Modernization program addresses shortcomings within the current DMS system,” Hertzog added.
Upgrades consist of improved antennas with advanced digital electronic support measures, or ESMs along with software components designed to integrate new technologies with existing B-2 avionics, according to an Operational Test & Evaluation report from the Office of the Secretary of Defense.
