Type IX U-Boat

History of Type IX Submarines

The German Marines paid a heavy price for their operations during WWII, most of their Type IX ships were lost at sea and most were on board. The Type IX was an effective fighting force, especially early in the war, and its presence was felt throughout the remainder of the conflict, as some 283 were completed and commissioneda total that was second only to Type VII This ship offers excellent range, powerful armament and durability, allowing her to fight in the relentless rough waters of the Atlantic Ocean. She was classified as a naval battle and did not disappoint her crew.

Her own class spawned four different sub-variants, each with upgrades. Type IX was formerly a class VII submarine.

The Type IX is derived from the MS ships of the First World War and developed from the earlier Type IA of 1934-1935. The new type differs in the use of a double-shell structure. The double hull structure allows for greater internal capacity by placing fuel storage and ballast tanks outside the primary hull and within the secondary watertight hull. Additionally, this hull design provides better crew and ship structure survivability as it absorbs potentially lethal blast forces more effectively. The design also provides enhanced performance when operating in volatile surface elements.

The Type IX's number of torpedoes has been increased to 22, along with its 6 launch tubes, making it a deadly performer of any size. Despite this offensive onslaught, the primary goal of the Type IX design was to increase the submarine's operational range.

The success of the progressive design came at the expense of reduced maneuverability and increased dive time.

The Atlantic waterways were extensively used by the Allies to smuggle troops, weapons and supplies into Europe to the detriment of German interests, a front both German leader Adolf Hitler and British Prime Minister Winston Churchill knew to win. Germany began developing long-range submarines to counter the growing threat of U.S. involvement in the war, and developed submarines with enough endurance to monitor and attack ships on the U.S. east coast.

From the very beginning of the war, Model IXs were seen flying over the Atlantic, and they focused their energies on operations on the East Coast of the United States and the South Atlantic. The main target was unprotected ships crossing the Atlantic before it was necessary for them to contain proper self-defense weapons or be part of a centralized escort strategy. Although this effort was successful, Type IX was eventually replaced by Type VIC. As the war progressed, Allied countermeasures improved significantly, radar and sonar systems and air patrols became more frequent and concentrated, and U-boats were placed on the defensive.

At the end of the war, escort and escort also caused the loss of many U-boat crews.

The Type IX as a whole has a sleek, slender and streamlined shape in keeping with the times. The empennage was set approximately midship, and the deck gun was located forward of the turret (the gun was sometimes omitted). The turret itself accommodated anti-aircraft weapons to allow rapid response by riflemen. These two positions are on the rear of the trainable stand.

The sails were equipped with appropriate periscopes and sighting devices. Vents dot the long sides of the IX design. The upper surface of the hull is flat so that the crew can pass through its top, while the sides are slightly angled outwards to accommodate the necessary internal compartments. The design tapers to a streamlined spine along the bottom of the hull, suitable for traversing deep waters.

The twin shafts are located in the stern, and there are systems on each side of the hull, each with a three-bladed propeller. The rudder assembly is mounted under the stern and controls the lateral maneuvering of the submarine as required. Anchors are placed along the sides of the bow. There are a total of six torpedo tube compartments, four of which are mounted on the bow side and two on the stern side.

The snorkel allows the Model IX to charge its battery while remaining below the surface. The crew consisted of 48 men - 4 officers and 44 seamen from the German Navy.

533 mm (21 in) torpedo-centred weapon (IXC). Capable of carrying 22 of these, coupled with the Type IX's endurance, the ship can stay on the battlefield for extended periods of time, while locating and tracking enemy convoys and ships, at the most opportune moment (on the water, usually on the night) attack. ). Six loaded torpedoes are stored internally and the rest in external torpedo "carriers" - two of these are stored in the bow and the remaining three are in the stern, accounting for about 10 additional torpedoes.

Each tube is full and ready to fire (6, front 4, rear 2) for a total of 22 torpedoes in reserve.

The deck gun consists of a Utof 105mm/45 gun and 110 usable projectiles, capable of engaging unarmed or lightly armed surface ships as much as possible. This submarine (Type IXC) is defended by 37mm anti-aircraft guns and 20mm anti-aircraft guns in a single trainable armament, also in a single trainable armament. The anti-aircraft gun system is layered along the rear of the sail, providing an excellent arc of fire in this arrangement. It is worth noting, however, that this air defense arrangement varied on Type IX ships throughout the war.

For example, sometimes deck guns were abandoned in favor of additional anti-aircraft systems, and some single 20mm mounts were changed to quad mounts.

Taking the IXC model as an example, the maximum speed of the ship is 18.2 knots and the underwater speed is 7.5 knots. Their range is nearly 15,535 miles along the surface and about 72 miles underwater. Dimensions include a length of nearly 252 feet, a beam of 22 feet 2 inches, and a draft of 15 feet 5 inches.

She had a surface displacement of 1,120 tons and a submerged displacement of 1,232 tons. Ground power is provided by two 4,400 hp MAN M9V40/46 compressor 9-cylinder diesel engines. Underwater battery power comes from two 1,000 hp SSW GU345/34 double-acting electric motors.

These systems drive two propeller shafts fixed to the stern of the design.

Type IXA is the first of Type IX. Eight of these ships were built by DeSchiMAG (AG Weser) in Bremen, Germany, and were in service in 1938-39.

AG Weser played an important role in the construction of German submarines during the First World War and by that time had merged with eight other German shipyards to become part of Deutsche Schiffund Maschinenbau AG (DeSchiMAG), and the AG Weser name continued as A separate name brand identifier may be. The shipyard eventually survived the war and continued to produce various ocean-going vessels until it closed on December 31, 1983.

Type IXA submarines ranged from U-37 to U-44. Armament includes six torpedo tubes, 1 x 10.5 cm deck gun, 1 x 3.7 cm anti-aircraft gun and 1 x 2 cm anti-aircraft gun. Her 22 torpedoes can be replaced by 66 mines.

From 1943 to 1944, the 10.5 cm deck was often omitted and replaced by additional anti-aircraft guns. Of the eight ships that went to sea, six sank between 1939-43 and two in May 1945 (U-37 and U-38).

While the Type IXA series is operating on water, the Type IXB is already in development. The series consisted of about 14 ships, ranging from U-64 and U-65, U-103 to U-111 and U-122 to U-124, in service from 1939 to 1940. These submarines are also produced by AG Weser at Bremer Werft. Essentially, the Type IXB is a modified vessel designed to further improve the operating area inherent in the Type IXA design.

Ultimately, the Type IXB team would prove to be the most successful of all the Type IX series, leaving behind many submarine aces. 22 airborne torpedoes can be replaced by 66 mines. By the end of the war, almost all Type IXB ships could sink an average of 100,000 tons of cargo.

All Type IXB systems were lost except for the U-123, which was decommissioned at Lorient on June 17, 1944.

Type IXC was added to the line and quickly became the largest operating group for IXC vessels. The building was again taken over by AG Weser and 54 such examples were made during the war. The IXC type is equipped with additional internal fuel storage to further enhance the submarine's range.

The IXC type can also be equipped as a minecraft, using either 66 TMB or 44 TMA series mines, although most are not normally equipped with such equipment. This group includes U-66 to U-68, U-126 to U-131, U-153 to U-166, U-171 to U-176, and U-501 to U-533.

The IXC type is barely surpassed in the IXC/40 type group. The range and surface speed of these ships have been improved, and there are 87 in total. Construction was carried out by AG Weser, Deutsche Werft (Hamburg) and Seebeckwerft (Bremen).

Submarines are U-167 to U-170, U-183 to U-550, U-801 to U-806, U-841 to U-846, U-853 to U-858, U-865 to U-889 and U-1221 to U-1235.

Most IXCs were sunk at the end of the war. The IXC was in service from 1941 to 1942, and the IXC/40 was in service from 1942 to 1944.

Development started as early as 1940, and the Type IXD was launched in 1942. The hull length of these boats has increased by 35.4 feet. Three sub-variants make up the type IX variant itself, named LCD1, LCD2, and LCD2/42.

Two Type IXD1s (U-180 and U-195) were delivered, but they lacked any viable armament (no torpedoes, just deck guns and seven anti-aircraft guns) and were instead used as ocean-going tankers for other operational U-boat. The Type IXD1 could carry around 250 tonnes of fuel and was criticised for being inconsistent with its experimental diesel engine - the latter implementation was not used in the Type IXD that followed. The engine is a 6 x 20-cylinder 4-stroke Mercedes-Benz MB501 "V" diesel system producing up to 9,000 hp.

These were later replaced by a pair of Germaniawerft F46 supercharged 6-cylinder four-stroke diesel engines. Underwater power comes from 2 x SSW GU345/54 double-acting engines rated at 740 kW. U-180 was lost west of Bordeaux on 24 August 1944 and U-195 was captured by the Japanese on 6 May 1945.

Type IXD2 includes 28 ships, the majority of the entire Type IXD. These offer ever-increasing range to an impressive 36,290 miles. The Type IXD2 can operate as far as Japan and the Indian Ocean, making it one of the deadliest submarine systems to date.

The number of torpedoes has been increased to 24 (or 72 mines). Operations ran from 1942 to 1944, and most were sunk before the end of the war.

Model IXD2/42 is nearly identical to the previous Model IXD2, but features an improved engine with more power - about 1,000 hp more than the original Model IXD2. According to reports, only two LCD2/42 systems are available for repair. On March 30, 1945, U-884 was damaged by an Allied bomb while still in the shipyard.

U-883 surrendered at Wilhelmshaven on June 21, 1945.

Type IXD submarines consisted of U-177 to U-182, U-195 to U-200, U-847 to U-852, U-859 to U-864 and U-871 to U-876. The U-883 and U-884 were the only two LCD2/42s. Construction of U-885, U-886, U-887 and U-888 had begun, but their progress was completely interrupted on September 30, 1943, when the LCD2/42 treaty itself was cancelled.

From 1943 to 1944, torpedo tubes were removed from many LCDs in service.

U-505 is an IXC submarine that can be seen in its full glory at the Museum of Science and Industry in Chicago, Illinois, USA. It was fully restored in 2005. The only surviving ICX type is the U-534, which can be seen in Birkenhead, England, UK.

The Type IX was eventually replaced by the X-class submarine.
