New FFM
The is a frigate class planned to be built for the Japan Maritime Self-Defense Force. These were reordered from 10 s, which was planned to have 22 ships before being scaled back to 12. The order for the new ships increased in quantity, and a total of 12 ships are to be built over a five-year period from the fiscal year of 2024. Background and development The Japan Maritime Self-Defense Force began constructing the (30FFM) frigates from 2018. These vessels were designed for mine countermeasure operations in addition to various littoral missions currently undertaken by destroyers and destroyer escorts of the 10th Escort Squadron, which is not part of the Fleet Escort Force. The original plan was to build 22 ships to replace the eight destroyers and six destroyer escorts of the 10th Escort Squadron, as well as the eight minesweeping vessels of the Mine Warfare Force (Japan), Mine Warfare Force. However, on 25 January 2023, the Defense Acquisition Agency announced the "Guidelines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mine Warfare Force (Japan)
The Mine Warfare Force belonged to the minesweeping force for the self-defense fleet of the Japan Maritime Self-Defense Force, Maritime Self-Defense Forces. Its main task is to lay naval mines in the event of an emergency, and it also helps to dispose of mines installed during World War II. 1st Mine Warfare Force With the Surrender of Japan, surrender of 1945, Japan was demilitarized based on the Potsdam Declaration, and the Imperial Japanese Navy was also dissolved. However, at the end of the war, 55,347 moored minesweepers of the Japanese Navy and 6,546 minesweepers of the Allies of World War II, Allied Forces remained in the waters near Japan. Based on the instructions of the Supreme Commander for the Allied Powers, Commander-in-Chief General Headquarters (GHQ), a minesweeping department was set up by the Military Affairs Bureau of the Ministry of the Navy on September 18, and 6 local minesweeping departments and 17 local minesweeping branches were set up on October 10.

Anti-submarine Missile
An anti-submarine missile is a standoff missile, standoff anti-submarine weapon, often a specialized variant of anti-ship missile. Anti-submarine missiles usually include a jet engine, jet or rocket engine, rocket engine and a warhead aimed directly at a submarine. In these missiles, a torpedo or a depth charge is used as a warhead. The anti-submarine missile can be either a cruise missile or a ballistic missile. History Depth charges were the earliest weapons designed for use by ships against submerged submarines. These explosives were initially dropped as the ship moved over the presumed location of a submarine. Before World War II, shipboard sonar was unable to maintain contact with a submarine at close range. Various mortar (weapon), mortar-type projectors, including hedgehog (weapon), Hedgehog and squid (weapon), Squid, were devised during World War II to allow a ship to maintain sonar contact while lobbing explosive charges toward the submarine. During the Cold War, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 07 Vertical-launch Anti-submarine Rocket
The is a Japanese ship-launched anti-submarine missile. Description In fiscal year 1991, the Japanese began developing an extended-range version of the RUR-5 ASROC to exploit the greater direct-path range of the new low-frequency OQS-XX and OQS-2x sonar systems. Following the end of the Cold War, this new anti-submarine missile yielded a complete improvement over prior systems, including not only simple range extension but also an improvement in responsiveness. The missile is fired from Mark 41 vertical launching systems and is capable of reaching supersonic speeds. It is controlled by an inertial guidance system and uses thrust vectoring. Its maximum range is said to be over .

Standoff Missile
Standoff weapons (or stand-off weapons) are missiles or bombs which may be launched from a distance sufficient to allow attacking personnel to evade the effect of the weapon or defensive fire from the target area. Typically, they are used against land- and sea-based targets in an offensive operation. The name is derived from their ability to engage the target while standing off outside the range at which the defenders are likely to engage the attacker. Typical stand-off weapons include cruise missiles, glide bombs and short-range ballistic missiles. Standoff missiles belong to the larger class of ranged weapons and are complemented by the Stand-in Attack Weapon (SiAW), a missile with a shorter range that is fired by an aircraft after penetrating enemy airspace. List of weapons * Air-Sol Moyenne Portée (ASMP) (French air-launched nuclear missile) * AGM-28 Hound Dog * AGM-69 SRAM (Short-Range Attack Missile) * AGM-84H/K SLAM-ER (Standoff Land Attack Missile-Expanded Response ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Combined Diesel And Gas
Combined diesel and gas (CODAG) is a type of propulsion system for ships that need a maximum speed that is considerably faster than their cruise speed, particularly warships like modern frigates or corvettes. Pioneered by Germany with the , a CODAG system consists of diesel engines for cruising and gas turbines that can be switched on for high-speed transits. In most cases the difference of power output from diesel engines alone to diesel and turbine power combined is too large for controllable-pitch propellers to limit the rotations so that the diesels cannot continue to operate without changing the gear ratios of their transmissions. Because of that, special multi-speed gearboxes are needed. This contrasts to combined diesel or gas (CODOG) systems, which couple the diesels with a simple, fixed ratio gearbox to the shaft, but disengage the diesel engines when the turbine is powered up. For an example the new CODAG-propelled s of the Royal Norwegian Navy, the gear ratio for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
