“What is the likely follow on from this?”
War on the Korean Peninsula, of course. You’re certainly not going to win North Korean “hearts and minds,” by an attack that is barely a step above typical terrorist tactics. This strikes me as an incredibly reckless and short sighted strategy.

LOL @ doppler radar Maws tracking F-22 Shots
Is there something special about the F-22’s missiles?
I believe it is more than comparable to the Block 50+ F-16 in terms of avionics (has an AESA, and we know the Japanese are no slouch when it comes to electronics :)), but I believe it is a rather heavy bird (the wing area probably helps make up for this in STR). Someone on here (Sens or Swerve I think) had a good report on the F-2’s capabilities and development written by the RAND corporation.
In any event though, I believe it is not available for export- in general Japan does not export military hardware and it is a very expensive aircraft.
THE F-32 LEWINSKY I can see it now
I believe the proper nickname was “Monica.” 😀
Read up on how RAM works.
RAM has been around since WWII as it was first used to eliminate multipath for RF communications systems. Properly designed RAM uses quarter wave cancelation in addition to its ability to turn RF energy into heat and an electrical charge. Quarter wave cancelation is where the return from the inner surface (groundplane) is 180 degrees out of phase with the return from the outer surface. This requires the distance between RAM outer surface and groundplane (where it is bonded to the substrate) to be one quarter of the wavelength of the frequency to be canceled. Most outer mold line RAMS are optimized for X band which is 2.5-4 cm wavelength. Also take surface inclination with respect to the threat emitter into account and you can calculate RAM thickness. I guarantee the answer is not 0.03mm
AFAIK carbon fiber can be used to construct Jaumann absorbers. This could be done with a hollow structure with the dimensions you have specified, which would cut greatly down on weight. X-band would give a distance between layers of less than 1 cm.
CF is a lossy dielectric and does not significantly attenuate RF energy. If lossy dielectrics were good RF attenuators, your microwavable chicken dinner (a lossy dielectric) would be raw in the center. :p
Hmm… Perhaps it depends on the fiber. This particular fiber is described as having “high electrical conductivity”:

For the record though, I did just eat a microwaveable dinner and indeed it was cold in the center. I was disappointed. 😀
RAM uses conductive particles to convert RF energy into heat and electricity.
Name a non-metallic material that is an efficient electrical conductor that can be used in an aviation environment. No such material exists.
Carbon Fiber as well as carbon nanotubes. Carbon fiber is often used in RF absorbers. Also a wide range of frequency selective surfaces can be constructed from metallic meshes.
I would think the Super Hornet is the obvious choice, is it not?
I thought that the Su-47 had a stated RCS of 0.1 m^2.
It is a photoshop. I forget the artist, but as I recall, the background is actually a gymnasium.
“Composite” is a general term referring to a vast number of materials of varying compositions (as I’m sure you are aware). In aerospace, carbon fiber (followed by kevlar perhaps) in a plastic matrix seem to be the most widely used composites. CFRP (carbon fiber reinforced plastic) is not transparent to radar. You can actually construct composite RAM directly without having to resort to coatings by optimizing fiber angles, widths, etc… as well as the fiber and matrix compositions.
Phantom II,
I think that the total number of M2k’s flying around the world is much less than 600.. I estimate the number in operation outside France to be somewhere between 230-250 and falling , the UAE are trying to get rid of their Mirage’s and I read somewhere that also TAIWAN was not very happy with their M2K’s acquired in 90’s and has been asking the US urgently for new VIPER’s ever since .The Mirage 2000 came late in 1984 at a time when the VIPER was already flying in high altitudes .
The assembly line was closed not because DASSAULT wanted to promote the more capable RAFALE ,it was closed because after the year 2002 nobody was seriously interested in MIRAGE 2000 anymore. The more versatile arche rival Block52+ was cheaper to acquire and operate. Since the fighter is no longer in production,the upgrade costs of existing fleets are extremely high ..
India and Brazil were certainly interested in late model Mirage 2000’s.
Ah, thanks for the clarification, Danell.
Erkokite
you could be right in the design, i dont know
as i read it when there are multiple suppliers, there are multiple names
this indicates that Thales North America Inc. is the sole supplier and supplies the whole system…
“SPECTRA integrated electronic warfare system”
or they would have has just MMIC’s if this was the case and then named other suppliers that built other partsComponents / Fasteners
Ateliers De La Hte. Garonne Solid Rivets:Aeronautical rivets; Bolts: Aeronautical bolts; Screws: Aeronautical screws
Avibank Mfg. Inc. Fasteners: Pins, bolts, fasteners & accessories
Ho-Ho-Kus, Inc. Fasteners: Clamps and fasteners, nuts, bolts & screws
Materials / Composites
Hexcel Composites Carbon Fibre: Carbon fibers, structural adhesives, honeycombs, prepregs, sandwich panels and reinforcement fabricsMagnolia Plastics, Inc. Syntactic Composites:
adhesives, coatings and syntacticsAirframe Systems / Weapons Systems
Thales Airborne Systems Surveillance/Air Defense Radar: RBE-2 active electronically scanned array radarThales North America Inc. Electronic Warfare Systems: SPECTRA integrated electronic warfare system operating in electromagnetic, laser and infra-red domains
You may be right in that they supply the final, assembled SPECTRA system. However, Thales USA likely sources many parts from other subcontractors as well- could be from France, USA, the UK, etc… They could actually do nothing at all other than assembly/integration for all we know. It may be possible as well that Thales moved the SPECTRA development team to the US at some point after they were privatized, but if French export controls and security clearance regulations are anything like those of the US, then most of SPECTRA’s development would still have to be done by French nationals. It could be somewhere in between. Thales USA may do integration, test, and some development, but the highly classified stuff isn’t done outside of France. Like you said, we don’t know. We’re just speculating really.
