U.S. Marine Corps Col. Matthew Kelly, military assistant to the Assistant Secretary of the Navy for Research, Development and Acquisition, provides background on the Marine Corps’ F-35B program to Air Marshall Bollam, Chief of Defence Material Air, United Kingdom, aboard USS Wasp while embarked in the Atlantic Ocean May 20, 2015. The current Marine Corps operational test, scheduled to continue through the end of May, will assess the integration of the F-35B while operating across a wide array of flight and deck operations, maintenance operations and logistical supply chain support in an at-sea environment. A former test pilot and career Marine aviator, Kelly participated in the earlier shipboard developmental tests of the F-35B. Royal Navy and Royal Air Force pilots are scheduled to begin flying the F-35B from the UK in 2018, and are on track to operate from the Queen Elizabeth Class aircraft carriers in 2020. - U.S. Marine Corps Col.

A sailor aboard the USS Wasp (LHD-1) signals to the pilot of an F-35B Lightning II Joint Strike Fighter to land as it arrives for the first phase of operational testing, May 18, 2015. The short take-off, vertical landing capabilities of the F-35B are crucial to the mission of the Marine Corps and necessary for operation aboard a Navy amphibious ship. The aircraft are stationed with Marine Fighter Attack Training Squadron 501, Marine Aircraft Group 31, 2nd Marine Aircraft Wing, Beaufort, South Carolina and Marine Fighter Attack Squadron 121, Marine Aircraft Group 13, 3rd Marine Aircraft Wing, Yuma, Arizona.
