L3 Technologies won a $73.7 million contract in support of the submarine photonics mast programs. The deal provides for repair, upgrades and overall services.
A photonics mast is a sensor on a submarine that functions much like a periscope but without requiring a periscope tube. This prevents water leakage in the event of damage. The Navy started fitting photonics masts to the Virginia Class submarines in 2004.
The Naval Sea Systems Command contracted L-3 with $48.7 million in 2015 to develop and build a new, slimmer version of its photonics mast for the Virginia Class submarines. In the boats, traditional periscopes have been supplanted by two Photonics Masts that house color, high-resolution black and white, and infrared digital cameras atop telescoping arms. L3 will perform 98 percent of the work in Northampton, Massachusetts and is expected to be finished by June 2025.
