A pretty aircraft, looking very much like a Do-17Z/Do-215, but there's no historical scenario in which to use it. I agree with GJE. I'd rather have a better modeled Do-215 first.

the what-if scnearios are what it could be used for. But yeah, no real priority. Just if someone wants to have fun modding it.

There is no historical scenario for XZFSU-1, nevertheless, it is great addition to Il-2, so I cannot agree with you. Let us to decide modders freely.

I have some stats for the T-18B from another project.


Model: Saab T-18b
 
Technical Description:T-18B was intended as a torpedo version of the Saab 18, therefore the "T" in the name. But due to technical problems with the torpedo they decided to arm it with a 57 mm bofors cannon instead which became it's trademark.
 
Short History: The development started in 1941 when the Swedish air force needed a new torpedo and marine attacker plane. First torpedo trials where done with the Saab 17 and later the Ju86 but none where satisfactory. Saab then proposed a torpedo version of the New Saab 18 that was developed at the time. It was first designated Saab T-18D but later in 1944 it was re designated to T-18B. It was first to be developed from the B-18A that was powered by 2 twin wasp engines. But it was later decided that it would be developed from the B-18B that was powered by 2 DB 605B engines. Nr 18164 (B-18B) was chosen to become the prototype. While Saab was constructing the prototype many tests was done on the ground. Shake tests was done to the torpedo that was planned to be used on the T-18B, along with the smoke bomb m/39. They tested if 2x 40 mm bofors cannons could be mounted in the nose instead of the 57 mm but the nose glass shattered. Nr 18164 first flew on the seventh of July 1945. Tests where done with a 53 cm torpedo along with some other smaller torpedoes, a 1000 kg bomb, some mines and rockets. The smaller torpedoes where impossible to drop because of the high speed T-18B flew at. And the 53 cm torpedo that was designed to be dropped at high speed had to be dropped at altitudes below 15 m above sea level. The torpedo concept was soon dropped since missiles where on it's way. The T-18B ended up as an attacker and the torpedo never saw service.
