Lockheed Martin has been awarded $150 million in follow-on production contracts for Marine Corps AH-1Z attack helicopter sensors.

Under the contracts, the company will provide Lots 13 and 14 of the AH-1Z's Target Sight System. The award also includes options for Lots 15 and 16, which if exercised would bring the total value to $284.6 million, according to a Lockheed Martin news release.

The Marines have bought more than 100 Target Sight Systems since 2008.

"The advanced capabilities and proven reliability of TSS provide the U.S. Marine Corps with a technological combat edge," said Paul Lemmo, a Lockheed Martin vice president. "Its long-range precision strike capability significantly enhances the helicopter's lethality and aircrew survivability."
