STRYKER

This is a photo of LAV (Light Armor Vehicle) Memorial in Marine Corps Camp Pendleton, California. Camp Pendleton houses SOI (School of Infantry) which owns LAV training. Our custom molded rubber components are being used in LAV, and I was told that the part was absolutely instrumental in activating a fleet of US-led coalition LAV in Iraq/Kuwait. Wow, that's cool. 

If you are in the market for the ultimate RV, this is it. It only costs around $2.5 million from General Dynamics. It weighs about 38,000 lbs, carries 11 people and 4 days worth of their stuff, climbs over 2 feet tall obstacles or 60% incline, goes 60+mph, has run-flat tires on 4x8 or 8x8, can go upto 300 miles in a single fill up, can be fitted with slat armor, it is IED proof, fits in C-130, C-5 or C-17. They can be flown in anywhere in the world with only 3 days lead time.

C-130 and Decoy Flares

Another cool thing at Marine Corps Air Station Camp Pendleton is rows and rows of aircrafts in Navy/Marine flat gray. The official photo and video are of a couple of Marine Corps KC-130 firing off their countermeasures, airborne infra red decoy flares. The flares are used to confused the heat seeking Surface-to-Air Missiles.  We are proud to know that the US Marine Corps is an end-user of our molded rubber component used in coutnermeasure flares. (Photo by Lance Corporal Andrew Z. Williams, Navy NewsStand - Eye on the fleet)

Super Cobra and Hellfire Missiles

This is a photo of AH1W Supercobra (whisky cobra) and a pod of hellfire missiles.  Camp Pendleton is the current home of Marine Aircraft Group 39 which was activated in Quang Tri airfield, Republic of Vietnam in chaos of war. No matter where you are on the base, we ca hear the cobras on the way to and from aviation target range. Every 5 minutes or so there would be a hellfire launch with an unmistakable hollow "wump" sound as it tears a hole in the air and whips it around into a vortex on its way to the armored target. The Cobras are made by Bell Textron, and hellfires are made by Lockheed Martin. We are proud to know that the US Marine Corps is an end-user of our molded rubber component.
