The US Navy has awarded Astronics Test Systems (ATS) a follow-on five-year production contract worth $36.4m for the supply of radio frequency distribution and control system (RFDACS) for its fleet of submarines.

Under the indefinite-delivery, indefinite-quantity contract, ATS will manufacture, test and deliver the RFDACS and related spare parts.

With this new contract, the company will deliver production systems and spare parts to the US Navy for five more years.

The RFDACS is a cruicial subsystem, designed to automatically route RF signals and information between the various antenna systems and other submarine communication subsystems, and forms an integral part of the common submarine radio room.

"This follow-on production award is a testament to the quality and reliability of the complex RF Subsystem we delivered to the US Navy."

Astronics CEO and president Peter Gundermann said: "The RFDACS is deployed on all active Virginia-class and Los Angeles-class submarines and designated for all future Virginia-class submarines.

"This follow-on production award is a testament to the quality and reliability of the complex RF Subsystem we delivered to the US Navy. We are pleased to have been selected again to support the men and women of our Naval Forces in meeting their mission."

Astronics is aiming to ship its $4m backlog from the previous contract by the end of this year.

ATS has been providing RFDACS and associated spare parts to the US Navy for more than ten years.
