Thing is, the short range nuclear strike squadrons are really in addition to the existing forces as I see it. This is a mission that NATO-UK didn't need, but Red UK would.
So we'd need even more "Harriers" than that. Probably some 300-500 based in England to strike across the channel into France and Denmark/Netherlands.
Did you see the 15 Jaguars squadrons? They can also do short-range nuclear strike. ITTL there were 40 squadrons in the late 1970s, but 25 converted to Tornado IDS during the 1980s.
Having written that, the Red UK's plan for World War III may be to invade the North of France in support of the Soviet-led invasion of West Germany. In that case another 1,000 Harrier GR.1 to T.4 instead of an equal number of Jaguars may be better as they can cross the channel and operate from improvised forward air bases faster than the Jaguars.
Also ITTL the Red UK's plan for World War III may include invading Norway in support of the USSR instead of the OTL plan which was to reinforce the Norwegians. They'll also want to take the Faroe Islands and Iceland to clear the already compromised ITTL GIUK Gap.
Though this could be a bunch of Su-24s or TFR-equipped Buccaneers as well.
Although I dislike the expression
"bunch of" as much as I despise
"target" as a verb,
"load out",
"swap out", "stood up", "multiple", "sport's" when they mean
"sport" or
"sport's" and mathematics abbreviated to
"math" instead of
"math's" - did you notice the 55 squadrons of Tornado IDS (plus 5 to be formed on mobilisation) and 10 squadrons of Buccaneers in the list?
- The former were Su-24 analogues, which replaced some of the Jaguars, the overland-strike Buccaneers and the surviving Vulcans.
- At its peak there would have been 25 Buccaneer squadrons in the Red RAF of which 10 were maritime strike (taking the place of the RN Buccaneer squadrons) and 15 were overland strike squadrons (replacing the Canberra and TSR.2).
- The overland-strike Buccaneers were the standard RAF version of OTL, but ITTL there's the money to have them built with a TFR.
Fellow children of the 1970s may be familiar with the phrase
"four bananas make a bunch and so do any more" which I'm rounding to five as it makes the arithmetic simpler.
- 11 bunches of Tornado IDS with a twelfth to be formed on mobilisation.
- 2 bunches of Buccaneers.
- 3 bunches of Jaguars.
- 3 bunches of Harriers.
That's 20
"bunches of" and as a banana tree only produces one bunch during its life, that's 20 banana trees worth or one copse.
I suspect that it was yet another case of the boffins were constantly fiddling with the UK sonar and kept saying it wasn't ready yet. UK industry was notorious for that. Constantly trying for "perfect" when "good enough to do the job" is what was needed.
I've not heard about Type 22 having US-made sonars. I thought sonar was one piece of equipment that was always British. That doesn't mean that
@Martes' statement isn't true.
It could also be because the UK was making them in smaller quantities and it was more cost effective to build a few medium size batches rather than several small batches. However, ITTL the larger quantities being built allow a few large batches or many small batches.
However, I suspect that rather than buying American they'd keep making the old British sonar until the new British sonar was ready. E.g. with radars the Type 965 radar was kept in production for 5-10 years too long and aught to have been replaced by a radar in the Type 1022 class about 5-10 years earlier. That's something that aught to happen ITTL. Then in turn we have Type 1022 replaced by Type 1030 in the first half of the 1980s.
