WASHINGTON, D.C. — Leaders in the F-35 Lightning II Joint Program Office and the Air Force F-35 Integration Office testified on the fifth-generation aircraft’s development before a House Armed Services subcommittee Oct. 21 on Capitol Hill.

Fielding a number of questions from Tactical Air and Land Forces Subcommittee representatives, Lt. Gen. Christopher Bogdan, the F-35 program executive officer, and Maj. Gen. Jeffrey Harrigian, the F-35 Integration Office director, Headquarters Air Force, assured them the program is making progress.

“The F-35 program today is executing well across the entire spectrum of acquisition, to include development and design, flight test, production … and building a global sustainment enterprise,” Bogdan said. “The program is at a pivot point today, where we are moving from slow and steady progress to what I call a rapidly growing and accelerating program.”

Overall, the program has flown more than 42,000 hours, including the international jets and the U.S. service-specific variations.

The F-35 is a complex program made more challenging by the fact that it’s still in development, even as we are flying it in the field. Recent tests on the safe-escape system revealed a problem that would result in lighter-weight pilots possibly suffering major neck injury upon ejection.

“The program is working with our industry partners on three specific improvements that will provide lightweight pilots that same level of protection and safety as all other F-35 pilots,” Bogdan said in his written testimony. “These three improvements are: one, a reduced weight helmet that weighs 6 ounces less than the current helmet … two, a pilot ‘weight switch’ on the ejection seat that reduces the opening shock of the parachute by slightly delaying the parachute’s opening for lightweight pilots; and three, a head support that will be sewn into the parachute risers that will reduce the rearward head movement of the pilot when the main chute of the ejection seat opens, reducing the pilot’s neck loads.”

Comparing the F-35 with the F-16 Fighting Falcon’s maneuverability was another concern; however, both generals were confident in the F-35 program and its capabilities.

“The F-35’s technology is designed to engage, shoot and kill its enemy from long distances, not necessarily in visual ‘dogfighting’ situations,” Harrigian said in his testimony. “There have been numerous occasions where a four-ship of F-35s has engaged a four-ship of F-16s in simulated combat scenarios, and the F-35s had a clear operational advantage because of the sensors, weapons and stealth technology. The F-35 has been optimized for the current trends of warfare, where the enemy is engaged and defeated from long distances, but it will still be able to maneuver aggressively when required to defeat and kill threats.”

“As with any big, complex program new discoveries, challenges and obstacles will occur; however, we believe the combined government/industry team has the ability to overcome current issues and future discoveries in order to successfully deliver the full F-35 capability to the warfighter,” Bogdan said. “The Joint Program Office will continue executing with integrity, discipline, transparency and accountability, holding ourselves accountable for the outcomes on this program.

“We recognize the responsibility the program has been given to provide the backbone of the U.S. and allied fighter capability with the F-35 for generations to come, and that your sons and daughters, may someday take this aircraft into harm’s way to defend our freedom and way of life. It is a responsibility we never forget.”
