			 The flight tests took place about 100 miles off the coast of 
			Norfolk, Virginia, in crosswinds of about 40 knots, and included the 
			first night flights at sea with a redesigned helmet made by Rockwell 
			Collins Inc and Israel's Elbit Systems. 
			 
			The high-risk flights also tested the jets' ability to take off with 
			less airspeed, with after-burners and with heavier loads of 
			simulated weapons. During normal F-35C launches, a jet goes from 
			zero to 150 miles per hour, traveling the 310-foot length of the 
			catapult in about two seconds. 
			 
			The results will set the standards for fleetwide F-35C catapult 
			launch settings for the service life of the aircraft, said Joe 
			DellaVedova, spokesman for the $391 billion weapons program, the 
			Pentagon's most expensive arms project. 
			 
			U.S. Navy Rear Admiral John Haley, commander of Naval Air Force 
			Atlantic, said developmental testing of the F-35C, the carrier 
			variant of the new stealthy fighter jet, had been "pretty doggone 
			good" compared with earlier aircraft. 
			
			  “We’re basically two years from being operational,” Haley told 
			reporters aboard the ship known as "Ike," which recently completed a 
			nearly two-year period in dry dock maintenance. 
			 
			Navy officials said developmental testing of the F-35C is about 80 
			percent complete, with a third round of even more difficult at-sea 
			testing planned next summer. 
			 
			The Navy will be the last of the U.S. services to start using the 
			new jets, following the Marine Corps, which declared an initial 
			squadron combat-ready in July, and the Air Force, which is slated to 
			follow suit in August 2016. The Navy is expected to have a first 
			combat-ready squadron in late 2018. 
			 
			Haley said the F-35 C-model would provide a "huge benefit" to U.S. 
			military commanders in coming years, working in tandem with Boeing 
			Co F/A-18E/F Super Hornet fighter jets and EA-18G electronic attack 
			planes for years to come.

			He said the jets' ability to fuse data from a variety of radars and 
			other sensors, and then share it with ships and other aircraft, 
			would change the way the U.S. Navy fights wars. 
			 
			"The F-35 is going to bring ... sensors and an ability to guide the 
			fight, whether it's an air-to-ground fight or an air-to-air fight. 
			They’re going to have an ability that’s going to change how we think 
			about getting to the target, delivering weapons and getting out of 
			the target," Haley said. 
			 
			Navy Commander Tony Wilson, one of five test pilots involved in the 
			tests on the Eisenhower, said he thought last year's first round of 
			tests on the USS Nimitz, and the jets' participation in a recent 
			integrated test with other aircraft, had helped reverse previous 
			lukewarm support for the program. 
			 
			He said it was also a huge advantage that the new aircraft could 
			easily be upgraded since it is software-based. 
			 
			"I think the Navy is going to be excited to see the tactical 
			performance of the aircraft," he said.
