Mark 36 SRBOC
The Mk 36 SRBOC (Super Rapid Bloom offboard Countermeasures, about German: from board shot down very quickly deploying countermeasures ) is a decoy system for maritime use. The full name is Mark 36 Super Rapid Bloom offboard Countermeasures ( SRBOC ) Chaff and Decoy Launching System, but also Mk 36 DLS ( Decoy Launching System) or Mk 36 called Super - RBOC. With the conversion to the final decoy generation, the name was changed in Mk 53 DLS.
The Mk 36 is a development of the Mk 33 RBOC with expanded capabilities. The system is used by at least 19 Marines and comes in various designs and developments ( " mods " ) available. The last model at the moment is the Mk 36 Mod 12
Development and construction
The SRBOC was originally developed by United Defense, now part of BAE Systems Land and Armaments and is in operational use since 1977. By the year 1999, about 848 systems were produced. The estimated cost of a Mk- 36 system with two cannons in 1999 were at $ 500,000, with four launchers at around $ 800,000. The Mk -36 systems are also being procured.
The complete Mk- 36 system consists of at least two Mk -137 launchers, each with a power supply Mk 160 Mod 1 and an ammunition magazine Mk 5 or Mk 6 per launcher, the launch control Mk 158 Mod 1 or Kk 158 Mod 2 in the operations center ( combat information Centre, CIC short ), which is usually connected to the system for electronic warfare AN/SLQ-32, the bridge controller Mk 164 Mod 1 or Mk 164 Mod 2, and a number of different types of ammunition. The SRBOC can be controlled from the bridge and from the CIC.
The SRBOC usually comes with larger surface units used. So on ships to 166 meters long (500 ft) is usually used a pair of launchers, where larger units are correspondingly more.
A single Mk -137 launcher consists of six launcher tubes are arranged in two parallel rows. The pitcher will be built in two versions for use on the port side and starboard and weighs 207 kg unloaded. While up to and including all of the tubes were arranged Mod 1 at a 45 degree angle, the tubes 45 and at angles of 60 degrees, oriented in the Mod 2. From each of the mortar -like tubes the decoys are fired in the caliber of 130 mm. Since the launcher or launcher tubes are not orientable and so the ammunition is fired at a fixed lateral and vertical angle, the vessel must maneuver to align the launcher to the intended objective. The ignition of the propellant charges via electromagnetic induction. The muzzle velocity of the decoys is with the Mk -137 launcher at around 75 meters per second.
The Mk- 160 power supply converts the 440 -volt alternating current of the electrical system of the ship in the DC required for the operation of the launcher. The operation is then performed with 28 V DC, can also be made via the built-in batteries with 24 V DC emergency operation for a period of five to eight hours but.
Development
By now, most SRBOC systems were modified so that they can also use active radar decoy type Nulka ( SRBOC Mk53 DLS). In 1994, a contract for the development of an acoustic one-way decoy torpedoes at Loral Hycor was awarded by the U.S. Navy, which was to be shot down over the Mk 36.
Decoys
As a decoy aluminum strip or coated carbon fiber can be included to provide missiles with radar a false target (called chaff or chaff ), or burning phosphorus, aluminum, magnesium, or combinations (so-called heat torches or flares) to missiles with infrared homing head a false target to offer.
When Mk 36 are used:
- Super Chaffstar (radar )
- Super Hiram III (infrared)
- Super Hiram IV (infrared)
- Super Gemini ( radar / infrared)
- Super LOROC (Long - Range offboard chaff ) rocket -assisted Chaff. The Super LOROC can bring the decoys at a distance of up to 2.5 kilometers from the ship.
- NATO Seagnat (radar / infrared), in different versions such as Mk 214, Mk 216, Mk 245 Giant ( infrared) or TALOS. When using the Mk 214 and Mk 216 Mk- 137- thrower must be cleaned after every shot because strong combustion residues remain in the launching tubes.
- NULKA, an active ECM - charge rockets to stabilize flight duration extension (only with modification of the thrower )
Specifications
- Tube length: 62.23 cm
- Total amount charged: 152.4 cm
- Muzzle velocity: 75 m / s
- Fire Control System: Mk -164 bridge control; Mk- 158 fire control ( Mod 1, 2 and 8) or AN/SLQ-32-Konsole ( mod 5 and 6)
