UK HTP Torpedo continuation

[zen]

So how do things progress if the UK doesn't abandon HTP Torpedoes in 1959?
Well since the data was handed to Sweden and results in a successful product, the answer is fairly obvious.
By designing a new torpedo around the HTP system, possibly using ceramic storage or purified metal for the HTP.
Perhaps this might also have seen the refridgeration of HTP stumbled onto and applied.

A curious possibility is that HTP making a good rocket fuel, is that the UK might be lured into resurrecting Bootleg-like or a their own Shkval-like weapon.

If such a decision, would the UK still sell that technology to Sweden?
Or could some sort of licenced Swedish production happen?

Torpedo development post-war was a fiasco!
Buying US weapons cut off the lessons learned from Dealer-B and stopped a host of other developments, the weapons that did continue were either seriously delayed or cancelled due to serious issues.

There were lots of innovative ideas for warheads, fuzes and powerplants but they couldn't make them gel together.
They could barely get Ongar/Tigerfish operational after 20 years of development, to throw in HTP would seem to make this task impossibly tougher and more expensive.

Had HTP been mastered, it may have smoothed powerplant issues but guidance would still have been a serious problem and may not have reduced development time that much. The Tp 61/611 arrived into Swedish service in 1964, the Tp 61/612 with 85% HTP doesn't seem to have arrived until circa 1970 (released for export to Denmark in 1971 and Norway in 1972).

I wonder if HTP could have provided the high-speeds originally demanded for Ongar? The Tp 61/612 had a max speed of 45kt and a range of 18.5km at 45kts and 24km at 30kts. Tp 613 had a max speed of 45kt and a max range of 30km.
The original Ongar with internal combustion engine using high pressure oxygen as oxidant was specified for 55kts.
But certainly HTP would have provided more speed and range than the eventual zinc battery powered Tigerfish.

Could you expand on this further?

I will have to do some digging in my files.

One example is the NAST.5711 which became Stingray.
This contained a seawater battery, a pumpjet propulsor (to reduce cavitation and self-noise in shallow water) and torpedo control system which used frequency modulated sonar transmission with receiver signal processing (‘coherent homing’) for very high resolution of spatial detail in target echoes and to reduce reverberation in shallow water operations.
