The Frankenthal class boats belong to the third generation of German post-war minehunters. Just like the Hameln class (class 343), the Kulmbach class (class 333) and the Ensdorf class (class 352), the boats of the class were built on the basis of the standard platform, which provides a uniform hull for all four classes. Due to the different tasks involved, the Frankenthal class differs from the other boat classes mainly in the area of the superstructure. The mine hunting boats of class 332 replaced the mine hunting boats of the Lindau class (class 331).
tasks
The main task of a mine-hunting boat is to find and destroy sea mines . Due to their equipment, it is also possible for the boats to carry out an exact mapping of the seabed; In addition, numerous parts of the wreck can be located in order to record them for shipping. In addition to mine clearance, the boats are also able to serve as a mine throwing platform.
Procurement history
The tactical-technical requirement for class 332 was drawn up in 1980; the AEG and MBB groups of companies created the definition with delivery in the spring of 1987 .
Class 332 was developed parallel to class 343, design and construction was carried out by Messerschmitt-Bölkow-Blohm GmbH, Munich, STN Systemtechnik Nord GmbH, Hamburg, Arbeitsgemeinschaft (ARGE) 343, Bremen, and ARGE MJ 332, Bremen, executed.
ARGE MJ 332 and ARGE 343 each consisted of the companies Fr. Lürssen Werft GmbH & Co. KG, Bremen, Abeking & Rasmussen Schiffs- und Yachtwerft GmbH & Co. KG, Lemwerder, and Krögerwerft Rendsburg GmbH, Rendsburg.
The first individual draft was for a mine-hunting boat with a displacement of about 400 t; the prime mover system should consist of two drive diesel engines KHD BA 12M 814 LLK-R with 600 kW (816 hp) each, two controllable pitch propellers on two shafts and an additional electric drive for crawl speed. The electrical machine system should consist of a total of four diesel generators. The effectors were a 40 mm L / 70 type 58 gun and a near-range anti-aircraft missile system RIM-116 RAM , and the sensors were either the optronic PEAB 9 LV 100 or the radar, infrared and laser-based PEAB 9 LV 200 MV2 provided.
The contract between the Federal Office for Defense Technology and Procurement (BWB), Koblenz , and the general contractor (GU) was signed on September 30, 1988. The construction contract for the first ten mine-hunting boats to ARGE MJ 332 took place on November 24, 1988. The construction contract for two more took place on October 13, 1995, GU were STN Atlas Elektronik GmbH, Bremen, and ARGE MJ 332, Bremen .
Technology, equipment and data
Shipbuilding description
The hull and the superstructure are made of non-magnetic chrome-nickel-manganese-molybdenum-nitrogen shipbuilding steel and the longitudinal frame and transverse frame system was used during construction. The minehunter has a semi-submerged forecastle, ten watertight compartments and NBC protection.
The mine hunter has an operational displacement of 650 t with a length over all of 54.40 m, a width over all of 9.20 m, a construction draft of 2.50 m and an operational draft of 2.60 m.
The mine hunting boat has two drive diesel engines MTU 16V 396 TB84 with 2,040 kW (2,775 hp) each, two shafts with two Sulzer-Escher-Wyss variable pitch propellers with diameters of 1.90 m each and two high-performance fin rudders . Three electric diesel engines MWM with 230 kW (312 PS) each and three generators with 160 kVA each complete the machine system.
The total design output is 4,080 kW (5,550 PS), the short maximum total output is 4,480 kW (6,090 PS). The slow travel speed is 2 to 6 knots, the cruising speed 12 knots and the maximum continuous speed over 18 knots.
The minehunter has a fuel supply of 60.29 m 3 .
The sensors are NBD navigation system, radio direction finder, Raytheon SPS-64 L-band radar device , GPS-Navstar satellite navigation system, system for evaluating and displaying tactical data in mine fighting (SATAM), data evaluation and information system (DAISY), and mine-hunting system Atlas Elektronik MWS 80-4 and Sonar Atlas Electronics DSQS-11M are available.
As additional equipment, the mine-hunting boat has magnetic self-protection (MES), two mine-hunting drones STN Systemtechnik Nord PINGUIN B3, mine diving equipment, diving pressure chamber, telescopic board crane, a dinghy, four life rafts and two bow anchors in side ducts.
crew
The minehunter can accommodate a crew of up to 44 people. In addition to the general soldiers, such as navigators, signals, sonar controls and technicians, the crew also includes specialized mine divers, for whom a diving pressure chamber is available, among other things.
Armament
As already mentioned, the boats were originally equipped with a 40 mm / L70 gun on the forecastle. However, these weapons were replaced on all boats by a marine light gun (MLG) 27 in order to improve self-protection. Furthermore, two air defense systems FIM-92 Stinger (Fliegerfaust 2) are available for air defense.
At least two MG3 machine guns , three G36 rifles , three MP2 submachine guns and two P8 pistols , hand grenades and one single-barreled and one double-barreled signal pistol are carried on board for guard and security tasks.
Mine hunting equipment
Originally, all mine hunting boats were equipped with the Sonar Atlas Elektronik DSQS-11M with a controllable search sector of 90 ° and the mine hunting drone STN Systemtechnik Nord PINGUIN B3. The recorded data is evaluated with the system for evaluating and displaying tactical data in mine fighting (SATAM).
Since 2010 all ten boats have been converted from PENGUIN B3 to SEEFUCHS. First of all, the boats Dillingen, Homburg, Sulzbach-Rosenberg, Fulda and Weilheim were modernized. The Dillingen was also equipped with the Integrated Mine Countermeasures System (IMCMS) from Atlas Elektronik. On December 21, 2016, Atlas Elektronik was commissioned to convert the last three boats. This includes the replacement of the command and weapon deployment system by the IMCMS, the replacement of the PENGUIN weapon system by SEEFUCHS for mine hunting and the transfer of the ability to control the SEEHUND surface drones to the simulation rooms. This means that ten class 332 mine-hunting boats will be available in the future, which will map mine-hunting, mine-clearing and mine-diving capabilities for anti-sea mine defense.
28 mine destruction charges are available for mine control.
Mine throwing device
The minehunter is able to hold up to 20 sea mines (anchor rope and ground mines), which can be thrown from the aft deck if necessary .
squadron
Originally, all twelve boats of the class belonged to the 1st minesweeping squadron , as this squadron was intended as a class 332 type squadron. In 1999, however, there was restructuring, after which the boats Frankenthal , Sulzbach-Rosenberg and Bad Rappenau were subordinated to the 3rd minesweeping squadron. When the 1st minesweeping squadron was decommissioned on December 22, 2005, the remaining nine units were transferred to the 3rd and 5th minesweeping squadrons. At the end of 2015 the 5th MSG was also dissolved, so that the last two boats of the squadron were placed under the 3rd MSG. All mine defense units are therefore bundled in the 3rd MSG.
Others
Originally the class should be called Weiden -class, since the Weiden was the oldest boat of this type; however, the Frankenthal was put into service earlier than the Weiden , although it was laid down later . In some sources, the name Weiden -class can be found parallel to the actual name.
