@SS:
Sorry that Tac hitting FS surfaced subs is nawing at me know. Why not just have Naval Dive Bombers can only hit surfaced subs. Can switch out US UK starting Tacs or most with Dive Bombers.
On that one, I would wait about forbidding Land-based TcB not being able to FS Subs with @3.
You are already splitting Fg from TcB.
IMO, DeHavilland Mosquitoes (UK’s TcB sculpt) was used in Anti-Sub mission.
They cannot be carrier-based as was the US TBF Avenger.
Coastal Command had seven squadrons equipped with the FB.VI, and later also received the 27 FB.XVIIIs. The Mosquitos were used for anti-shipping strikes, mainly against coastal traffic. Because this brought them within the range of land-based Luftwaffe fighters, good performance was essential. But the coastal convoys were also well protected with anti-aircraft guns, and attacks were dangerous.
The Mosquito fights the U-boats
From November 1943 on wards the Mosquito was also used to attack U-boats shortly after, or just before they entered a port. Warning of these opportunities was provided by code breakers. At that moment the U-boats travelled on the surface, and therefore were vulnerable to rockets or the 57mm shells of the FB.XVIII. For safety, the U-boats usually formed small convoys, with an escort of mine sweepers or so called Sperrbrecher ships, which had hulls reinforced with concrete as a protection against mines; both types bristled with anti-aircraft guns. For example, on 27 March 1944 six FB.VIs and two FB.XVIIIs attacked a convoy towards La Pallice, formed by U-960 with a escort of four M-class mine sweepers and two Sprerrbrecher vessels. Three mine sweepers suffered light damage, U-960 was badly damaged, two Mosquitos returned home with serious damage, and one crash-landed.

Also, TacB sculpts works for all Medium bombers with less range than StB, 4 engines bomber.
The B-25 enters battle …
The first unit to receive B-25s was the 17th Bombardment Group (Medium). After Pearl Harbour this moved to the west coast to fly submarine patrols, and on 24 December one sank a Japanese submarine. Later the 17th moved to the east coast, where they sank a German submarine. Other B-25s, including 40 originally built for the Dutch, were sent to the South-West Pacific area. Operating from bases in Australia and New Guinea, they tried to halt the Japanese advance. They were joined by a Dutch unit. Later other B-25s groups operated in the Central Pacific, and over the Aleutian islands. In June 1942, B-25s appeared in Burma, and in August 1942, the 12th Group began operations in North Africa, were they were joined by the 340th Group in March 1943. The USAAF observed that the faster B-26 was more suitable for operations in Europe, and operated the B-25 mainly in the Mediterranean and the Pacific.
As an early revenge for Pearl Harbour, one of the most unusual operations of the war was planned. Sixteen B-25Bs were modified by installing extra fuel tanks, for 4319 liters instead of the usual 2627. The volunteer crews received additional training. The bombers were loaded on the aircraft carrier USS Hornet, and on 18 April 1941, the bombers lead by Major J. Doolittle took off to their targets in Tokyo, Nagoya, Osaka and Kobe. The plan was to land in China, where the bombers would be a welcome reinforcement; but because USS Hornet was detected by the Japanese the aircraft had too take off early, and none reached its destination. Although damage was light and all aircraft were lost, the “Doolittle Raid” was a big boost for the American morale. It also was a serious concern for the Japanese, who became acutely aware that an American force could come to within strike distance of Japan almost undetected.
In 1942 a small number of B-25Bs was sent to Britain, which deployed them in North Africa and eventually in India. Operations in West Europe were postponed until the more capable B-25C arrived. The 2nd Group of Bomber Command flew its first mission on 22 January 1943, against oil storage facilities in Belgium. It soon adopted very tight formations for mutual support, and their aircraft retained the ventral turrets. The RAF continued to use the Mitchell until the end of the war, receiving B-25H and B-25J models. Total deliveries were 872, but a substantial number of these were sent to the Bahamas for anti-submarine patrols.
Some were also sent to the USSR. The USSR would receive 862 B-25s, and after the war the NATO allocated the type the recognition name Bank.
In the summer of 1942 the USAAF and the USN came to an agreement which allowed the Navy to operate land-based bombers. In early 1943 the Marine Corps began to receive its first B-25Cs, which were given the Navy designation PBJ-1C. On 17 March 1944 the “Flying Nightmares” of VMB-143 flew their first operational mission, against Rabaul. A total of 706 aircraft were delivered to the USN and USMC. These aircraft were painted grey, or later sea blue. Radar was installed, and depending on the type it was under the aft fuselage, on the wing tip, or in the nose. Their normal armament consisted of depth charges, but they could also carry a torpedo. Nine USMC squadrons used the PBJ-1 in combat.
