Wasn’t there a conversion kit to make the J model? How about the turbo powered Tracker? Wasn’t that Taiwan?

Not really maritime patrol but might help sprout some ideas.

I have mused a couple of times about the RAN keeping their Trackers in service longer using a turboprop conversion and an avionics update.

The Taiwanese AIDC S-2T is one example of that TPE331-powered Turbo Tracker conversion. But, oddly, the S-2T Turbo Tracker has a bunch of Canadian-made electronics - eg: the Litton Canada AN/APS-509 search radar (although some sources claim AN/APS-504) and the CAE AN/ASQ-504(V) MAD antenna.

So, a subtle whif would be an S-2T style electronics/sensor fit on a PT6A-powered Conair conversion.

a PT6A-powered Conair conversion.

Which conversion is that?

Given the TPE331 Turbo Trackers have 1227 kW (1645 shp) turboprops, something similar on the PT6 side would probably require either a -67 or -68 variant or even PT6T Twin pack.

Conair Turbo Firecat, PT6A-67AF
Built in Abbotsford, BC, first one flew in 1988.
The conversion kit link I posted is for this type.

Ah ok - so a -67F which aligns to what I was thinking.

Of course, there's also this route:

Cool! But also prompting a few questions:

- The twin tails on the Design 215 were to better handle the T64s' extra power?

- Both Design 165 and Design 215 were intended to be new-builds, right?

- Any reason that the Design 165 couldn't have been a Tracker rebuild programme?

I'm wondering about the feasibility of an earlier-than-OLT CP-121 upgrade (since the CF had T53s in their CH-118s and CX-84).

I'm wondering about the feasibility of an earlier-than-OLT CP-121 upgrade (since the CF had T53s in their CH-118s and CX-84).

Being as Designs 121, 137 (tanker), 142 (COD) and 165 were relatively straightforward
re-engined developments of the Stoof, it could be a rebuild program. T53s were proposed
for all including the original 165 proposal which was changed to T55s.

Interesting note from Francillon's Grumman Aircraft since 1929:
"In 1987, the Canadian Department of National Defense announced that IMP Group in
Dartmouth, Nova Scotia, would re-engine a CP-121 with 1,059-eshp Pratt & Whitney
PT6A-67AF propeller-turbines driving six-blade propellers and that this experimental
conversion was likely to be followed by the re-engining of twenty-seven additional aircraft.
The re-engined CP-121s will probably be fitted with Spar Falcon FLIR (Forward Looking
Infra-Red), Litton Canada APS-504(V) radar, and Marconi Canada ARV-509(V) Omega
very low frequency navigation equipment."

... and pigs will fly.  ;D

Thanks Jon. And interesting to see the electronics/sensor fit planned for the CP-121 update. My guess is that the CP-121 update died because nobody at DAR 3 made a priority of an inshore MPA programme.

One puzzle there was why DND was so committed to the Omega nav system (I know that the CP-140s has Omega receivers as well).* Since almost all of the Omega transmitter stations were in the southern hemisphere, it doesn't seem to make a lot of sense. Maybe the US was extra protective of GPS back in the '80s?

The Pakistan Navy's Sea Sultan MPA which is based on Embraer’s Lineage 1000E business jet, which is itself a variant of the Embraer 190 regional airliner is an attractive looking platform:
