Are the F-16C Block 32s in the USAF inventory still operational?

Block 32 has small inlet?

Can you guys give me any units that have operating the Block 32.

Thank you.

Yes, the 32, 42, and 52 have the "small mouth" inlet.

The ANG unit in Fresno, CA? (Perhaps?)

After the BRAC I believe they may be the only ones? Almost all the Vipers with PW-220s will be gone, namely Block 25s and 32s. The only other PW Viper bases will be McIntire (Blk52) Tulsa (Blk42 w/PW-229) Toledo (Blk42 w/PW-229) and Fresno (Blk32)...

Off the top of my head... Any others?

Tucson has 42's with 220's, least they did a few years ago.

64th Aggressors, 61st FS at Luke has 1 or 2 maybe?

Duluth MN ANG is still operating BLK 25s
Sioux Falls SD ANG has Blk 30 Small Mouths also
Fargo ND ANG was the last unit to fly Blk 15 ADF until Jan 07 when they converted to the Predator Sad

and C-21

Wouldn't all the Blk 42s at Luke count too! I'm not sure which squadrons will be operating them once the 25s retire, but from what I remember it is the 63rd, 308th, and 310th flying those models. They'll be around for the forseeable future.

The T-Birds were in 32s up until last year also. The aggressors at Nellis may use some 32s, but not the guys in AK.

Sorry, those would be "combat coded"; I wasn't thinking training or "special use"... Shrug

The last USAF "combat coded" PW (small-mouth) Viper unit was Block 52s out of Mt Home.

Yes Luke has some Blk42s, as does Nellis I believe. They may also still have some 32s at either or both locations, I'm not sure. There are most likely some 32s or 42s at Eglin or Edwards as well. Seems they have just about 1 of everything...

Anyone Question

The T-Birds still use 32s as well, their 52s don't come online until the 2009 season. This is the last season for them to have polished Turkey Feathers; unless they've figured out a way to chrome plate the carbon-fiber feathers of the PW-229.

The 61st had one block 32, it is now in Fresno at the 144th which is all block 32's. And it is rumored that the T-birds 2 seater will be going to fresno as well.

What is the difference between the exhaust of Blk. 25 to Blk. 32?

To an engine guy, probably there are some.....to us duffers, its the same motor. The 42s and 52s with the uprated -229 motors have the carbon fiber exhausts.....the 25s and 32s fly the same engine.

OK. Thank you guys. I hope someone with kind heart will post pictures (blk 25 & 32).

Nothing. Both the Blk 25 and 32 Viper use the F100-PW-220 or PW-220E engine. (The PW-220E is an upgraded PW-200) For the purpose of our discussion we can consider them identical as the PW-220.

The PW-220 has a nozzle assembly that consists of 15 titanium alloy external segments (Turkey Feathers). It appears a dull metallic color and has the "NO STEP" (forward end) "NO PUSH" (aft end) stenciling. You will also notice an area of flat gray "spray film dry lubricant" that is applied to the overlap region of each (lower or inside) segment.

Note: This nozzle type can also be found on Block 42s of the USAF that have not been upgraded to the newer engine; Older foreign PW-200 engines also have the same nozzle assembly, but very few exist as most have been upgraded to PW-220E.

The PW-229 has a nozzle assembly that consists of 15 carbon-fiber external segments. It appears as a flat black color and (typically) has no stenciling. They also do not have the lubricant applied in the overlap areas.

PW-229 engines are in the Block 52 and 52+ as well as the ANG Block 42s.

PW-220 example: http://www.f-16.net/gallery_item46740.html

PW-229 example: http://www.f-16.net/gallery_item46758.html

Except for the external segments, the rest of the nozzle assembly is the same in appearance and function. The augmentor duct liner has a few minor differences. There is noticeable difference in the flameholder, and the spray manifolds inside the front of the augmentor, (just aft of the turbine) but unless you have your head inside the nozzle, or are looking close from directly aft, you're not likely to see that.

Hope it helps...

Actually, there is. Block 25s did not come with the LEF RWR antennas, nor the C model vertical tail dorsal scoop/vents. Within the past few years, Block 25s have received ALE update, which consisted of adding the LEF RWR antennas, but the tails dorsal remains the same.

Now days, Mot Blocks 25s look identical to Block 32s, aside from the dorsal scoop/vents.

Ditto your enigne breakdown.

So read the question I answered. "What is the difference between the exhaust of Blk. 25 to Blk. 32?"

Again I'll say nothing, as the LEF RWR antennas and vertical tail dorsal scoop are NOT located on the EXHAUST of the Blk 25 or 32. Rolling Eyes

To further illustrate, the PW-220 or PW-220E engine of any Block 25, 32, 42(USAF) can be exchanged between aircraft without concern or regard. They are all identical in form, fit, function.

There are minor differences, but the engine would need to be uninstalled for one to notice. There can be clamping/wire harness routing differences, and there can be cover plates installed over the old upper air-oil cooler holes in older forward bypass ducts. (If they haven't been changed to the newer style ducts without the holes.) These are just two "visible" examples. In any case the longer a PW-220E is in service, the more and more it will resemble a production PW-220 as the parts are becoming more and more common between the two as they both mature into a "common" designation.

I do appreciate the "Ditto (my) engine breakdown"; even if you can't spell engine correctly... Poke
