These are the incredible four-tube night-vision goggles SEAL Team Six wore during the Bin Laden raid

The 2011 assault on Osama bin Laden's compound in Abbottabad, Pakistan exposed two of the US military's top-secret weapons programs, the MH-X Silent Hawk helicopter and highly modified night-vision goggles.

Each elite soldier on the raid was issued a pair of $65,000 four-tube night-vision goggles (NVGs), SEAL Team Six member Matt Bissonnette writes in his book "No Easy Day."

Bissonnette participated in the May 2nd, 2011 raid on the compound in which the Al Qaeda chief was killed.

"Unlike some of the conventional units, we had NVG's with four tubes instead of the usual two. This allowed us a field of view of 120 degrees instead of just 40 degrees. The standard goggles were like looking through toilet paper tubes," Bissonette writes.

The secret helmet-mounted system gave SEALs an unprecedented ability to see in complete darkness while navigating through the heart of enemy territory.

According to Defense One, the "Ground Panoramic Night Vision Goggles" are manufactured by L-3 Warrior Systems Insight division in Londonderry, New Hampshire.

The Pentagon has spent approximately $12.5 million since 2010 on this elite military eyewear, according to Defense One.
