...a swap 25 years ago seemingly without too much problem. So F404 and J52 must be of comparable sites. There are discussion about "afterburning J52s" on this forum. In fact the Viggen RM-8 engine was a scaled up - civilian - afterburning J52 ...

There was the PW1216 proposal. This was an after burning derivative of the J52-P409 engine proposed for the GrummanSabre II concept.

That afterburning J52 with 14000 lbs thrust on 2600 lbs would give a thrust/weight of 5. 4. For early 1960s: J79-8 17/3.6=4.7 Atar 9K 6700kn/1490kg = 4.5 How would the afterburning J52 be that superior? And if it was, why no takers?

My suggestion: if you need a J52 with afterburner, ask the Swedes for the Viggen engine. Through the civilian JT8D, it was exactly that: an improved, afterburning J52. Hmmm, a Skyhawk - Tiger - Viggen trio with the same basic engine, now that would be something to behold.

It seems that the J52 had a better thrust/weight than the non-afterburning J79 (CJ805-3). J52-P-8: 9,300lb thrust / 2,118lb weight = 4.4 T/W J79 (CJ805-3): 11,200lb thrust / 2,815lb weight. = 4.0 T/W Now add the afterburner section... the J79's AB section weighed ~700-850lbs and provided ~52%...

It's been a while, but wasn't there supposed to be an engine change, too, with the P&W PW1216 installed in place of the existing engine? PW126 was essentially an afterburning derivative of the J52 which would have made that a very adapted core, with turbojet, afterburning turbojet, turbofan...

That afterburning J52 is really tempting. Plus, the J52 could be driven hard to allow supercruise. That the RB106 wasn't developed makes me want to cry, however.

Plus the swedish connection - SAAB Viggen.

Note that Singapore's A-4s were all A-4B & A-4C models... they had the J65*, not the J52 (A-4Es and later only). J65-W-20 (A-4Cs, retrofitted to A-4Bs to replace 7,700 lb.s.t. -16s): thrust 8,400 lb.s.t.; weight 2,795 lb; length 130"; diameter 37.7"; SFC .90; airflow 120 lb/sec J52-P-408 (in...

I think we discussed the possibility of a J52 F-5 elsewhere, but seems to me it would be a pretty interesting option. Dry thrust varied from 8,500 lbf in J52-P-6 to 11,200 lbf ( and 12,000 for J52-P-409). So the single J52 was more/comparable thrust with a pair of J85 running on afterburner...

I think an afterburning J52 turbojet rather than J-79; J-79 is too big.

...- J52-408 had 11,200 lb.s.t.. J79 proposed (and tested) for the F-16/79 (-119) had 12,050 lb.s.t. dry - J52-409 proposed (and tested) for A-6G and reworked EA-6Bs had 12,000 lb.s.t.. The ONLY reason J79 had more thrust was its afterburner. That's why the answer to "AFTERBURNING J52 is "use...

J52 was scaled down from J57. It could have had a scaled down version of the J57 afterburner.

The J79 AB would be 800 lbs for +6000 lbs, the J52 AB 550-600 lbs for +5000 lbs? Atar AB also 900-1000 lbs... Maybe it is the lower design speed... but difficult to say, the afterburning J52 was never tested in a plane?

Did F-20 have notably more drag than F-5? Because in practical terms that's what a J52 F-5 is. An F-20 without the afterburner.

I didn't suggested that: rather, to get a J52 afterburner "for free" from the Swedes and, voilà, a competitor to the J79.

J85 was fuel hungry but *lightweight* J52 with afterburner would be more fuel efficient but heavier. For a strike aircraft, J52 makes sense - longer range is worth some extra weight. For a short-range air-to-air fighter, the extra weight might not repay itself in reduced fuel burn at cruise.

Okkaaaaay so I was looking at Aerion atempts at finding an engine for their SSBJ. It happens that they tried a smart trick related to the JT8D. Which was a civilian J52. And then Wikipedia mentionned it was used as basis for the Viggen engine. So that made it supersonic. Hence the core was both...

That would be nice but as usual I am thinking no AB on this to keep her speed in the Mach 1.1-1.2 range because of that US policy on restricting super fast jets in parts of the world. But given the Mirage is available I am reasonably sure that it will get the sale because of that policy.

An afterburning J52 would be J57 I think, but F-5 probably doesn't need an afterburner at the end of the day as Hound Dog was supersonic. It might want one to fight MiG-21 but that's why F-20 was made in the first place I guess.
