Sonobuoys Weaponry Depth Chargesthe most used weapon, were improved during the course of the war. Y-guns and K-guns were used to throw depth charges to the side of the escort vessel, augmenting the charges rolled off the stern and letting the escort vessel lay a pattern of depth charges The development of forward-throwing anti-submarine weapons such as Hedgehog and the Squid.
This allowed the escort vessel to stay in contact with the submarine during an attack. When the German Navy developed an acoustic homing torpedo, torpedo countermeasures such as the Foxer acoustic decoy were deployed.
Intelligence One of the best kept Allied secrets was the breaking of enemy codes including some of the German Naval Enigma codes information gathered this way was dubbed Ultra at Bletchley Park in England.
This enabled the tracking of U-boat packs to allow convoy re-routings; whenever the Germans changed their codes and when they added a fourth rotor to the Enigma machines inconvoy losses rose significantly. By the end of the war, the Allies were regularly breaking and reading German naval codes.
To prevent the Germans from guessing that Enigma had been cracked, the British planted a false story about a special infrared camera being used to locate U-boats. The British were subsequently delighted to learn that the Germans responded by developing a special paint for submarines that exactly duplicated the optical properties of seawater.
Tactics Many different aircraft from airships to four-engined sea- and land-planes were used. As more patrol planes became equipped with radar, U-Boats began to be surprised at night by aircraft attacks. U-Boats were not defenseless, since their deck guns were a very good anti-aircraft weapon.
They claimed Allied aircraft shot down for the loss of U-boats to air attack. The German naval command struggled to find a solution to the aircraft attacks.
At one point in the war, there was even a 'shoot back order' requiring U-boats to stay on the surface and fight back, in the absence of any other option.
Some commanders started charging batteries during the day to gain more warning from air attack, and perhaps gain time to submerge. One solution was the snorkel, which allowed a U-boat to stay submerged and still charge its batteries.
A snorkel made a U-boat more survivable and losses to aircraft went down. The Germans at the time had been using their Focke-Wulf Fw "Condor" long range aircraft to attack shipping and provide reconnaissance for U-boats, and most of their sorties occurred outside the reach of existing land-based aircraft that the Allies had; this was dubbed the Mid-Atlantic gap.
At first, the British developed temporary solutions such as CAM ships and merchant aircraft carriers. These were superseded by mass-produced, relatively cheap escort carriers built by the United States and operated by the US Navy and Royal Navy. There was also the introduction of long-ranged patrol aircraft.
Many U-boats feared aircraft, as the mere presence would often force them to dive, disrupting their patrols and attack runs. The Americans favored aggressive hunter-killer tactics using escort carriers on search and destroy patrols, whereas the British preferred to use their escort carriers to defend the convoys directly.
The American view was that defending convoys did little to reduce or contain U-boat numbers, while the British were constrained by having to fight the battle of the Atlantic alone for the early part of the war with very limited resources.
There were no spare escorts for extensive hunts, and it was only important to neutralize the U-boats which were found in the vicinity of convoys. The survival of convoys was critical, and if a hunt missed its target a convoy of strategic importance could be lost.
The British also reasoned that since submarines sought convoys, convoys would be a good place to find submarines.
Once America joined the war, the different tactics were complementary, both suppressing the effectiveness of and destroying U-boats. The increase in Allied naval strength allowed both convoy defense and hunter-killer groups to be deployed, and this was reflected in the massive increase in U-boat kills in the latter part of the war.
The British developments of centimetric radar and the Leigh Lightas well as increased numbers of escorts, reached the point of being able to support U-boat hunting towards the end of the war, while earlier on, the advantage was definitely on the side of the submarine.Established by the Chief of Naval Operations in , SHip Antisubmarine Warfare Readiness / Effectiveness Measuring (SHAREM) has conducted over site-and threat-specific exercises to gather.
