Project 12700 — Composite base minesweeper Alexandrite

Surface ship 12700 project — the largest ship in the present day with a composite body. Designed and created by the central maritime CB "Diamond" by order of the Russian Navy. The main purpose of the base or ship mine-sweeper defense — search and destruction of various types of mines with non-threatening distance to the ship itself. Base minesweeper ship project 12700 is the latest generation of CSI. This day is the construction of the first (head) of a ship "Alexander" for the needs of the Navy Russian Federation.

BT "Alexandrite" laid at the end of September 2011 at the JSC "SNSZ" under the serial number of the number 521. Initially, it was expected that the ship will come down the slipway in 2012, and July 27, 2012, at the celebration of the 100th anniversary of "SNSZ" company CEO announced that the final date for delivery of the vessel to the customer in 2013.

The arrangement and design
The main feature of the new ship — a unique housing (The largest in the world) one-piece fiberglass made by vacuum infusion. To ensure the creation of a unique case, the company zopoluchilo a range of equipment, which comes in the latest equipment, related software and the laboratory, which is built on the basis of the creation of the most experienced. On this day, the company "SNSZ"-the only thing on the territory of Russia, which has similar technology and able to produce ships solid body up to 80 meters.

The main advantages of whole body:
— overestimated in comparison with the strength of a conventional iron hull;
— inflated property of survivability;
— extended service life;
— light weight.

Length base minesweepers will be around 50-52 (according to other sources 70) meters and a displacement of 600-800 tons. Apart from this, the BT "Alexandrite" will receive the Mine circuit, made with new dies away, holding the highest efficiency. They will be located on the ship (in the integrated bridge systems and PCC) and remotely operated underwater vehicles and self-contained, and are intended for search, detection and destruction of various types of sea mines in the marine and coastal area. With the SCE will be automatically controlled mine system.

Also on the ship to establish normal minesweepers weapons and equipment. By implementing a set of thrusters BT "Alexander" will own the highest port and maneuvering characteristics. Not spared designers comfortable accommodation and crew rest — the ship equip with all necessary equipment and will create conditions for the rest, ensuring that the crew is very efficient delivery targets.

Detection and destruction min will be held at BT "Alexander" in a modern way using underwater bots operating on remote control of either offline ahead of the ship at the rate of repetition. The ship will hold the highest ranking features and will be able to carry out the detection of various types of naval mines with a 5-point scale sea state.

Another distinguishing feature of the project 12700 is the serial production of new boats and ships made on the basis of a unified whole body. On the basis of the new building can be frisky batch creation of patrol vessels for the various departments, support ships to perform different tasks and ships / boats for river fleets.

After a series of tests on at BT "Alexander" will rise in the Navy of the Russian Federation, and project 12,700 will go to the series. Serial number of ships of project 12700 for the time being it is not clear exactly.

The main properties (Due to the fact that the ship will be the first with the introduction of a longish composite body, its properties until the values are inaccurate):

Displacement — 600-800 tons;
— length — 50-52 (70) feet;
