NNSA, in collaboration with the U.S. Air Force Global Strike Command, recently conducted successful surveillance flight tests using a Joint Test Assembly (JTA) of the B61 Mod 7 (B61-7), B61 Mod 11 (B61-11), and the B83 strategic bombs.
“The recent JTA tests demonstrate NNSA’s commitment to ensuring that all weapon systems perform as planned and that systems are safe, secure and effective,” said Brig. Gen. Sandra Finan, NNSA Principal Assistant Deputy Administrator for Military Application. “The strong partnership between NNSA and Department of Defense is a vital part of our commitment to national security.”
A JTA contains instrumentation and sensors that monitor the performance of numerous weapon components during the flight test to determine if the weapon functions as designed. This JTA also included a flight recorder that stored the bomb performance data for the entire test. NNSA uses the data in a model, developed by Sandia National Laboratories, to evaluate the reliability of the bomb.
The NNSA-designed and built JTAs support the Joint Surveillance Flight Test Program between the Department of Defense and the NNSA to simulate the actual weapon configurations utilizing as much war reserve hardware as feasible. The JTAs are designed by Sandia National Laboratories/California. The JTA test components are manufactured at the Kansas City Plant are then assembled at the Pantex Plant in Amarillo, Texas. The NNSA Tonopah Nevada Test Range, where the tests were conducted, is managed by Sandia. JTAs are not capable of nuclear yield, as they contained no nuclear materials.
A B-2A Spirit stealth bomber from the 509th Bomber Wing, operating out of Whiteman Air Force Base, delivered and released the B61-7, B61-11 and B83 JTAs at the NNSA’s Tonopah Test Range in Nevada.
