Hull and superstructure
The ship is bult with longitudinal frames giving optimum resistance to arising stress forces. For safety reasons, the hull is divided into watertight sections, tanks, and cells. The shell plat-ing consists of ten all-welded strakes.
The main deck, which is the most important part for the overall strength of the hull, has a minimum number of openings. It is built with deck bends and sheers. Beddings are welded onto the main deck for torpedo tubes, a 57 mm dual-purpose gun, and a flare-rocket launcher.
The deckhouse consists of the actual housing, air-intake cap, and a shield beside the air intake. The whole deckhouse is built from light metal and riveted to the main deck.
Protection against NBC-weapons
For operation in NBC-contaminated areas, the Spica can be sealed until completely airtight. Air for the ventilation system is then taken via filters, and an overpressure is generated inside the ship. Operation of the ship and weapon systems can be managed from inside the ship without any personnel staying on deck.
Even the 57-mm gun can be fully operated without being manned, though with a limited ammunition supply for engagements.
Accommodation and food supply
The Spica offers ample space for accommodation. All crew members, officers as well as those enlisted, have their quarters in cabins.
Separate mess-rooms (gunrooms) are available for offi-cers, non-commissioned officers, chief petty officers, petty officers, corporals, and enlisted men.
In the ship’s kitchen, known as the “galley”, two cooks prepare tasty and balanced food for the crew. Officers have their meals served in the mess-rooms, whereas corporals and enlis-ted men are served directly from the bar in the galley.
Once during the Spica planning phase, an idea came up to rely on ready-cooked food and to install microwave ovens only. But we who have enjoyed the on-board service are very happy that common sense finally won!
