I believe they were also using A-4 and A-8 as fighter bombers?
Anyway the Stuka was still in use in the MTO through the fall of Tunisia I think. I'd have to go open up MAW to be sure to confirm the precise timeline though. Well, hell why am I so lazy it's just 5 feet away on the bookshelf. Hang on...
Ok I see a Ju 87D-3 Trop (from 9./StG 3)damaged in combat on
21 March 1943. 3 x Fw A190 A-4 from SKG 10 also damaged by bombs on the same day, so those like like they are fighter bombers.
Again on 24 March SKG 10 had a Fw 190A-4 crash landed 70% damaged with the pilot WiA, and a Ju-87D-3 trop of 9./StG 3 shot down and crash landed.
31 March two Ju 87s from StG 3 shot down, one by AAA, one by a P-40.
April 7 looks like 7 x Ju 87s from StG 3 shot down or heavily damaged, mostly by Spitfires. One Fw 190A-4 lost too.
April 15, a Fw 190 A-5 from SKG 10 was shot down by AAA and crash landed.
Looks like "Schnell kampf geschwader 10" (fast war squadron 10) was equipped with Fw 190s and one Stab deployed to North Africa in Dec 1942 or early 1943 - some pilots coming from ZG 2 (formerly with Bf 110s)
StG 3 was operating in North Africa since August 1941, with declining efficacy noted by the Second battle of El Alamein in Oct 42. They started taking very heavy losses, Wikipedia says on 11 Nov 1942 they lost 8 out of 15 aircraft to US P-40s. They moved to Sardinia on
April 18, 1943 and were withdrawn to Germany shortly after that.
I looked this up in MAW, it doesn't appear in MAW III for that day but there is a big massacre on Nov 11 in MAW II. It shows a loss of 14 aircraft - 5 x Bf 109, 4 x Ju 87, 1 x Ju 88, 1 x Do 17, and 3 x Ju 52, all to British Kittyhawks from 2 and 4 SAAF, 260 RAF, 112 RAF, and US Warhawks from 57th FG. The British lost 9 Kittyhawks (7 of these the older Kittyhawk 1 operated by the South Africans) shot down or crash landed, and one US P-40F. Several other Stukas and other German planes were damaged in the same engagement and subsequently destroyed by retreating troops.
Anyway, the Stuka was clearly on it's last legs by then. By this phase of the Mediterranean war, they operated sporadically and only when they could arrange for heavy fighter cover, but the escorting fighters would typically abandon them and climb away when Allied fighters arrived in force, leading the Stukas to eject their bombs (sometimes over their own troops) and flee for their lives. Stukas had such a good turn radius that they seemed to be pretty good at evading fighters in these cases, but obviously their effectiveness for strikes was greatly reduced.
