With a stock price that's up 0.8% after Wednesday trading, Hartford, Conn.-based United Technologies (NYSE:UTX) looks bulletproof today. Helping it get that way is a new contract that UTC subsidiary LifePort just won from the U.S. Air Force.

On Wednesday, UTC announced that USAF Special Operations has contracted with LifePort to outfit its fleet of Sikorsky HH-60G PAVE HAWK helicopters with a bulletproof Improved Ballistic Armor Sub System to protect helicopter pilots from ground fire. The PAVE HAWK is a variant of UTC's famed UH-60 Black Hawk helicopter, preferred by U.S. special forces.

According to UTC, LifePort is currently "the only company in the marketplace today able to" manufacture "qualified armored flight seat pallets based on strict USAF specifications." It's also apparently able to manufacture them quickly. UTC says it will have the entire USAF HH-60G fleet outfitted with the new ballistic armor before the end of September.

Financial terms of the contract were not disclosed.
