    Yeah, because without laser or EO/IIR it's decametric precision not metric.

    No, as stated, GPS decametric, laser/IIR metric. Plug your butt.

    So the pilot make a testimony where he use a low collateral weapon with a decametric precision?:butcher:

    Yes, a low collateral weapon with 10m CEP.

    AASM is more expensive than Brimstone now?

    Yep, how could it not be. Far larger weapon.

    10m CEP is not low collateral.

    But that is the accuracy of the GPS only SBU-38, as described in wiki.

    Again
    The problem with you is that we have to fight in order to simply share our knowledge.
    I know the functioning of the French DGA, I worked with them 33 years.

    When they decide a development they organize a competition with minimum specifications for the main characteristics: these are performances that must be reached under pain of penalties.

    But the companies that participate in the competition know that they have to offer the best they can do otherwise they have no chance of winning. The DGA then designates the winner and drafts the technical clauses of the future equipment with the performance that the company has proposed.

    But these technical clauses are generally classified so that the official performance of the system remains that of the tender even if they are much lower than those proposed by the company.

    The second problem with you is that you denie the possibility for non US companies to do better than US companies so if the inertial/GPS performance of the paveway is 10 m then the Hammer performance of the same has to be 10 m.

    But Hammer is more recent that JDAM and Inertial/GPS performance of JDAM is already 5 m

    http://characterisationexplosiveweapons.org/studies/annex-e-mk82-aircraft-bombs/

    And Safran is a specialist of inertial systems like Litton far better than Raytheon and it had get the help from Dassault for the design of the command and the aerodynamic. So there is no raison for them to be unable to improve the CEP compare to the JDAM.

    Also the precision of the military signal of GPS is classified, the 10 m is for the civilian signal it was the accuracy of the GPS at the time where the US suppressed the degradation of the civilian signal against the military signal, but from this time GPS accuracy has improved even if the civilian signal haven't improved. Gallileo accuracy is 1 m do you think that GPS III satellite still deliver, for PPS signal, a 10m accuracy only ? And to further improve the performance of the GPS one can use the GPS positioning solution, such as GNSS Augmentation systems.

    So technically there is a lot of possibilities to reach the metric accuracy, but BMD denie the possibility.

    As I am tired of fighting with him I will ignore his messages because it does not matter if he believes me, but I would respond to the messages of others if a constructive doubt is expressed.

    No, it's because 10m is the best accuracy achievable with GPS.

    Accuracy of laser is sub-metric.

    Oh here we go, French stuff is better than US stuff. Sure. They can hit an ICBM travelling at Mach 25, but French GPS is more accurate than theirs. The INS is only a back-up as your link states. With INS it's only accurate to 30m. The actual GPS system itself is only accurate to 7.8m with a 95% confidence interval at best and it depends on UERE assumptions, could be as bad as 12.3m. Sorry, not metric, no way, no how.

    Hardly compares to Brimstone going straight through the handbrake of a moving vehicle.

    Since your main point is the EF, you should have chosen this thread, also to get to a credible idea about the EF in the first place. Your opinion is largely based on a version that was on offer more than a decade ago.

    P1E is the operational standard, which is used in Syiria or Iraq today, P2E and P3E standards will be operational by the end of next year.

    Typhoon is not good. I explained in the Rafale thread.

    @Guynextdoor

    Course @Sancho has brought up some good points. The SK competition probably is too old for reliable information, but the Danish evaluations were last year.

    Besides, the typhoon isn't the only plane getting upgraded. F-35 block 3F, block 3 SH, Rafale F4 etc.

    I don't think the eurotyphoon has won a single competition yet.

    EF P3E
    Rafale F3R
    Gripen E

    Come all around 2019, the F18SH block 3 shortly after that and when you compare these versions, you will see a lot of differences to the past:

    http://indiandefence.com/threads/eurofighter-typhoon.4731/page-341#post-555863

    The Danish tender was issued some years ago and the EF won in Saudi Arabia and Kuwait, Oman wasn't a tender as far as I remember.
