Honeywell-Equipped F-35B Reaches Critical Milestone

The U.S. Marine Corps became the first service branch to reach initial operational capability (IOC) with the F-35B Lightning II. The announcement was made July 31 by The Unites States Marine Corps. Honeywell Aerospace is a member of the Lockheed Martin JSF team and provides more than 125 parts and sub systems for the world’s most-advanced multirole fighter jet.

“Achieving IOC is a critical milestone for the program and this amazing aircraft,” said Carey Smith, Defense & Space President for Honeywell Aerospace. “Congratulations to the U.S. Marine Corps on this achievement. We’re extremely proud of Honeywell’s contributions to the program and of the thousands of employees who have worked to make the JSF program a success.”

The IOC essentially declares that the F-35B is ready for combat operations. It was issued following a rigorous operational readiness inspection by the Marine Corps. IOC dates also have been established for U.S. Air Force and Navy operators.

Honeywell Aerospace provides five major subsystems for the aircraft including the Power and Thermal Management System (PTMS), which integrates auxiliary power, environmental controls and emergency power functions into a single system. This integration technology, which is a dramatic contrast to conventional systems, reduces aircraft weight and length while significantly increasing reliability.

Other major Honeywell contributions include the wheels and braking systems, navigation systems, life support and main engine fuel control system. In all Honeywell provides more than 125 unique parts for the aircraft; components are manufactured at 13 Honeywell sites worldwide.

The F-35 Lightning II is a fifth-generation fighter, which combines advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations and advanced sustainment. Three variants of the F-35 will replace the A-10 and F-16 for the U.S. Air Force, the F/A-18 for the U.S. Navy, the F/A-18 and AV-8B Harrier for the U.S. Marine Corps, and a variety of fighters for at least 10 other countries.
