Submarine structure, drone boats and molds.
The same mills, presses and metrology that build aerospace tooling build marine structure: structure for the nuclear submarine industrial base, composite structure for unmanned surface vessels at rate, and hull and deck molds at vessel scale.

Marquee program
USS Connecticut. Janicki built the replacement bow sonar dome for the Seawolf-class submarine two years faster than the next-best option, so the boat returns to the fleet on schedule. In October 2021, USS Connecticut (SSN-22) struck an uncharted seamount in the South China Sea, destroying the bow sonar dome. Puget Sound Naval Shipyard & IMF needed a precision replacement dome with no production line behind it, on the boat's schedule. Janicki delivered it 24 months faster than the next-best option because everything the job needed sits under one roof: 5-axis mills that fit a hemisphere, the metrology to prove it, and the 1,000-ton press that forms double-curved plate.

Structure for the nuclear submarine industrial base.
Sonar domes and precision machined hardware for the U.S. Navy's nuclear submarine programs, built on the same mills, press and metrology that machine a 100-foot hull plug in one piece.
Nuclear submarine programs
Sonar domes and precision machined hardware for a submarine industrial base that is being asked to build more boats per year than it has in decades.
Marine molds and plugs
Full-scale hull and deck plugs and production molds machined directly from customer geometry, plus deckhouse, hatch, appendage and fairing tooling for commercial, recreational and defense builders.
Drone boat production
Series production of composite structure for unmanned surface vessels (wings, keels, hulls, decks and assemblies) on Janicki-built tooling. For Saildrone, Janicki built the composite wings and keels for the 33-foot Voyager, a fleet that has logged 900,000+ nautical miles. With tooling, layup and assembly in-house, a design change does not wait on a second vendor.
