There's a new concept out there regarding basing that involves small packs of F-22s and a single C-17, maybe they are trying it out?

 

 

Yeah I've read that too. The article I read mentioned that it was an attempt to diversify in order to prevent catastrophic loss from a PRC first strike. So they're only stationing 4x F22s per base. Logistics must be a nightmare.

Given the overmatch, a single flight of F22s could cause insanely disproportionate losses on any conventional Air Force whenever they got airborne, the only limitation is the formation is too small for constant CAP.

True, but there's also the vulnerability against a commando raid with a small packet.

The Archies weren't particularly competent at anything else, what makes you think they were any less crappy at airfield defence? ;)

The Archies..., I had no idea that you are a clone and that your older clone brothers fought in The Falklands War ..... :o :P :P .

 

I would like to think that should the USAF deploy their most prized A2A asset in penny packets, globally, then their security and defence will be taken reasonably seriously.

Then again, I could be wrong.

Greetings everyone :D

 

hmm have anyone try POFACETS software ? That's a software based on MATLAB used to predict RCS. It use physical optics as its basic laws Thus it has limitation that it cannot predict RCS other than specular (The mirror like return which is the strongest but also having extremely narrow lobe that it can only be "detected" if geometry permit)

 

That also the very same ware that used by Carlo Kopp in his analysis to predict F-35's RCS.

 

In my hand however.. Well i used it to polish my own stealth fighter. The Shelenia Nativera.. Roughly a single engined YF-23A here

I converted the 3D model of it to RAW format that acceptable for conversion to .mat file and start the fun. My goal was to optimize at least frontal aspect RCS against X-band radar based on this reference :

 

 

The original model have well.. Since i make it for fun High frontal aspect RCS

The polar graph

Okay..optimization time.. so i changed some features in the mesh..like smoothing up the nose (reducing sharp edges and discontinuities) And the second mesh appeared..

The polar plot.

Better but still there are two disturbing lobes spawned.. Something went wrong.. So time to optimize again.

 

The last time.. i think i get it right :D

The mesh this time is much finer..ironed up some more discontinuities and sharp edges.

 

The RCS ?

I managed to get 0,01 Sqm at X-band :D Pretty fine i think.

 

 

Yes the software has limitations but I think it's adequate for conceptual designs and optimization of design before first metal or composite is cut.

 

Most importantly.. it's free (though the MATLAB is not)

 

I would love to repeat Dr Kopp's analysis but i haven't make any F-35JSF models yet and there are still some uncertainties regarding on how the analysis was done (e.g Why Dr Kopp simulate only a part of the aircraft instead making a complete 3D model of it)

The proposed Stealthy Super Hornets will carry a stealthy cernterline weapons pod. It weighs 900lbs and will have a 2300lbs capacity. Boeing have not ruled out the Hornets carrying an additional 2 on the inner wing pylons (that code for we're still testing).

 

I wonder whether Lockheed will come out with their own stealthy weapons pods for the F22/35.

That's Wake Island not Diego.

 

I stand corrected. Similar shape; even the airstrip is on the same south west part of the island. Much smaller though. Never looked at wake on a map before.

A company called Terma took the gun-pod from the F-35B/C (the A has an internal gun) and made it capable of carrying sensors and/or jammers.
