The wreckage of a US Navy fighter jet has been found after it crashed near Mount Rainier in Washington, and a major search continues for the two missing crew members.

The mangled EA-18G Growler was discovered around 12:30 p.m. Wednesday on a mountainside in an “isolated area that is not accessible to motorized vehicles,” according to Navy officials.

The $67 million jet from the Navy’s Electronic Attack Squadron crashed east of Mount Rainier around 3:23 p.m. Tuesday during a “training flight routine,” officials said, with the cause remaining under investigation.

The two crew members were still missing Thursday morning despite a massive search effort in rainy conditions, including the deployment of a US Navy MH-60S helicopter.

It was unclear whether the two crew members had successfully ejected before the accident, the Navy said.

The Navy and local agencies plan to send crews to reach the crash site and secure the area. Snow is expected in the Cascades through the weekend.

“I am grateful for the tremendous teamwork demonstrated by the NAS Whidbey Island squadrons… as Team Whidbey continues to respond to our tragic accident,” said Capt. David Ganci, Wing Commander. electronic attack on the American Pacific Fleet, in a press release.

“I am also grateful to local law enforcement, responders and tribal communities whose partnership has been essential in planning our critical next steps to access the site,” he added.

The Growler jet is part of the “Zappers”, also known as Electronic Attack Squadron 130 or VAQ-130. Most squadrons are based on Whidbey Island and another squadron is based at Marine Corps Air Station Iwakuni, Japan.

The “Zappers” were recently deployed on the USS Dwight D. Eisenhower.

The Growlers, which cost $67 million each, have operated around the world for the past 15 years in support of major military actions, according to the Navy.

“The EA-18G Growler aircraft we fly represents the most advanced technology in airborne electronic attack and is the Navy’s first line of defense in hostile environments,” the Navy said on its website.

The aircraft is flown by a pilot seated in the front and an electronic operator directly behind them.
