Antennas
Scandia has manufactured the parts for and has assembled virtually every antenna mast for every class of US nuclear submarine. Antenna systems include the AN/BRA-34, OE-207/BR, AN/BRD-7, BLD-1, HDR, OE-158, OE-538, AN/BQR-19, BPS-15, OE-305, BRR-6, AN/BRA-8, AN/BRA-9, AN/BRA-21, and NAVSAT. In addition, we have manufactured BRA-24 and BRR-6 buoys and floating wires and components for the OK-542 Thin Line Handling Equipment. Scandia has also manufactured the sail closure door systems for the AN/BRD-7(BLD-1), IEM, ACM & the HDR mast fairings.
Periscope Masts
Scandia manufactures and assembles periscope mast fairings for the 688 (Los Angeles) class, 726 (Trident) Class and SSN 21 (Seawolf) class Submarines. Work includes machining of all internal components in addition to the fit-up, alignment and installation of these components into the mast fairing. We routinely recondition and upgrade in-service masts, incorporating ECP’s and field changes. Some of the typical systems that we work on are the Type 2, 8J, 8L, 15L and 8B Mod 3.
Hydraulic Cylinders
Scandia manufactures various types of hydraulic cylinder assemblies including submarine antenna, snorkel and periscope mast fairing hoist cylinders and HDR antenna closure door cylinder assemblies. Typical materials are monel 400 for the cylinder and K-500 monel for the piston rod. All welding is done using approved procedures by welders qualified in accordance with MIL-STD-248D & NAVSEA S9074-AQ GIB-010/248. All cylinders are subjected to pressure proof and performance testing prior to shipment.
Valves
Scandia manufactures numerous types and sizes of valve assemblies including ball, needle, gate, globe and cartridge type checks. Typical applications for these valves are ship's hydraulic, high pressure air, diver's air and seawater systems. These valves are subject to strict test requirements prior to shipment. Scandia also manufactures gear operators, actuators and spare parts kits for these valves.
Connectors & Hull Fittings
Scandia manufactures SUBSAFE hull fittings and hull penetrators as well submarine stuffing tubes and electrical connectors. We have manufactured many of the connectors and other items in MIL-C-24231, MIL-H-21367, MIL-S-24235 and the penetrator for the Wide Aperture Array
Radar Masts
Scandia Manufactures AN/BPS-15 & AN/BPS-16 Radar Masts complete with all internal waveguide components. These masts are completely tested both hydrostatically and electrically.
Lifting & Handling Devices
Scandia manufactures & tests friction type antenna, periscope, radar, snorkel mast and hoist cylinder lifting clamps as well as mechanical lifting devices, spreader bars and lifting slings for the installation, removal and handling of all equipment in the submarine's sail. In addition Scandia has manufactured & tested submarine ordinance (Tomahawk & Harpoon) lifting and handling equipment.
Other
Scandia manufactures and assembles submarine machinery and structure ORDALTS and MACHALTS. These components are packed in ship set kits for easy shipment and installation. Previous kits include Periscope Well Modifications and Torpedo Ram Pump Ejection System.
Piping & Fittings
Scandia manufactures specialized CRES, CUNI and NICU pipe and tube fittings including filters, strainers, tees, drain/vents, test connections, elbows, couplings, reducers, inserts, air diffusers & water diffusers. These fittings are often classified Level I and require detailed certifications and special testing.
