I don't know about this aircraft, but a modern turboprop with A2D Skyshark performance (500+ mph) would most definitely be worthwhile, it could handle subsonic attack jets their ass in maneuverability, acceleration, endurance and be very close in top speed.

Concerning the "improved" PW127, 3% is paltry, you could get just as much efficiency from winglets on an ATR.Jump to post

I'm almost surprised they didn't slap a PW150 on it (think A2D Skyshark)Jump to post
Wow. That is the largest and most powerful CAS single engine prop since the A-1 Skyraider. In theory, a configuration like this should be capable of speeds in excess of 400 mph.Jump to post
The ATR doesn't need more efficiency, it needs more speed with the same efficiency. In particular, the ATR-72.Jump to post
At 239 ft they are clearly going for volume over total payload mass. That could bite them in the ass down the road. At 365T, how much payload are they sacrificing vs 778 length?Jump to post
I'm not sure why you think that the European countries are not paying for a credible defense.

Swiss find F-35 performs better than Typhoon in A2A Considering the Typhoon is faster, is designed for and can legitimately supercruise, has a better thrust to weight ratio, lower wing loading and superior kinematic performance to the F-35, I'm curious as to what metrics the Swiss used to evaluate ...Jump to post
Please not this again. Virginia is as quiet as a Seawolf. It may not dive quite as deep or be as fast but has more flexible weapons load with the VLS which Seawolf lacks. The important part is.... A 774 is literally half the cost of a Seawolf ... Better to have two Virginia than one Seawolf. If the...Jump to post
If they are more interested in air to ground, F-35 is probably the winner. Air to air and it should be the Typhoon's to lose. What does Spain need? My guess would be air defense primarily and strike a distant second. I'm thinking Typhoon.Jump to post
The Virginia class is in ongoing production while the Astute I believe has completed its class of boats. Certainly it can be restarted but easier to just join in, AKA like the P-8 is doing now.

The empty weight of the 777-F is 318K and the 777-300ER is 370K. So what is the maximum landing weight for both? I don't see how the -300ERCF comes close to making up 52Klb of extra airframe weight.

Now, if you built a civilian optimized freighter around the TP400 engines, that might be a winner but not the A400M as is. Same reason why the BC-17 didn't get very far.Jump to post
Technically the 747SP is the commercial airliner with the highest "econ" cruise speed at M.86 to M.88 IIRC. Definitely faster than the 787, A350 or A380. Mmo is still M.92Jump to post

777-8 is 229 ft. I say keep the freighter at that length. Are they purposely trying to kill the passenger version?

You all are assuming that the 77F has its available space used efficiently.

The EX is looking less and less like a true F-15C replacement and more of a move to fill the ANG with ground attack aircraft that happen to be able to fill the A to A role when necessary. AKA, the Strike Eagle.

The second seat position looks too low for a trainer. The WS-15 seems to be having the same problems as the Saturn Izdeliye-30. Stuck in a ~15-year-and-counting development hell.

If the 777-8F was going to be 772 length, definitely, but now that its looking to be close to (if not right at) 773 length, not so much IMO. WAY too much volume for a 777-based tanker. Fuel payload will suffer dramatically because of all that extra dead structural weight.Jump to post
The big question in my mind regarding the livery is if they use the Jackie Kennedy, will they keep the polished aluminum belly?

Using the RISE would give it a cruise speed essentially equal to the E2 but with 15-20% greater efficiency and consequently greater range.

I think it took too long to develop and the performance was less than hoped for - a little quicker and and a little better might have tipped the scale for several of the 744 airlines. Yes.

I'm getting more fuel, also realize lower wing loading means earlier cruising through thin air. However at ULCC densities, the range is reduced.

The V-280 is now getting more powerful Osprey engines. I think the MTOW of the design will be much higher than is currently listed.
