USS Helena to Start Its Maintenance Availability

Los Angeles-class submarine USS Helena arrived at Norfolk Naval Shipyard (NNSY), July 21, for a docking continuous maintenance availability (DCMAV).

The availability’s critical pathwork will focus on installing new electronics, inspecting the boat’s oil tank, and correcting any deficiencies that arose during deployment. The technology upgrades will include the installation of a modular framework of processors and consoles, high-resolution monitors, and large-screen displays.

Helena will be in dry dock until mid-October, which means the project team only has a few months to complete its renovations and repairs before waterborne testing begins. Helena is scheduled to depart NNSY in November.
