    R-60 can pull over 40-60G. Plus if it’s launched it would mean the target is well within visual range (some 10-20 Km at most) and can be as low as 300 m, of typical gunnery range. At such distance the R-60 is lethal and difficult to evade. Unless countermeasure is deployed (flare)

    I realize their publicity material states that the R-60 can pull 40-60 G but it has never been proved. Anyway that can be said about advertisement made by any defense prime.

    That said, even if the R-60 is fired from 10-20 Kms it still gives the enemy fighter enough time to carry out a hard turn and evade the R-60. Thereafter, it becomes extremely difficult for the R-60 to re establish a lock on and chase the target again. Even if it does establish a lock on, it is travelling at speeds of Mach 3 and above. Naturally at that speed it will run out of fuel before it reaches the target.

    Please note ,this applies not just for the R-60, but for its successor the Vympel R-73 and any other Air-to-Air missile or Surface to Air missiles fired by systems like PAC 3 or S-400. Plz do not let their publicity material convince you otherwise.

    The deal with the French was back in 09 as I remember it. At the time the suggestion was that SSN-BR would be something that evolved out of the Marlin SSK project. Itself a larger evolution of the Scorpene. I’m not sure Shortfin had actually arrived as a concept back then. It seems that SSN-BR has now shifted more towards a Barracuda class than the quasi-Rubis that wouldve resulted out of the originally mentioned concept. Not sure there’s much solid in the public domain about the deal.

    There was a poster here with a defence site solely keyed into the Brazillian scene, Zone Militar think it was called, perhaps he can offer a bit more insight?

    Thanks Jonesy.

    One last question about the Australian Shortfin Barracuda.

    Will the choice of a torpedo be dictated exclusively by the type of combat management system (CMS) & its associated torpedo fire-control system on the Shortfin Barracuda? Or will they be able to use torpedos from other countries like the US, for example the Mk 48?

    The reason I ask this is because French submarines like the Scorpene, generally use the SUBTICS CMS that are all programmed to accept only certain type of torpedoes for example Black Shark.So maybe they won’t be able to use other torpedoes like Mk 48, DM2A4 or the Spearfish.

    That being said I checked the website of Atlas Electronik and they state that the ISUS-100 CMS is a COTS PC based modular open system architecture. This means it can be configured for any type of submarine.

    https://www.atlas-elektronik.com/what-we-do/submarine-systems/isusr-100/

    I suspect the French CMS on board the Shortfin Barracuda is not based on open architecture which is why the Aussies will have to stick with French torpedoes like the Black Shark/F-21.

    It is for defense. The R-60 can pull very high G maneuver. It will do the turning for the MiG.

    If the R-60 or any other air-to-air missile is launched and it fails to hit the target, chances are that it cannot pull high G manoeuvres and re engage the hostile aircraft again,because by then the R-60 will run out of fuel.

    If that is the truth then the Aussies have just gone for the best dog & pony show regardless of vapourware content. Really hope, for their sake, the DCNS lads can deliver or they’re going to redefine the definition of ‘mugs’.

    Jonesy, wasn’t the Shortfin Barracuda also offered to Brazil by DCNS? Though IIRC the Brazilians went for a nuclear submarine which is supposed to be derived from the Barracuda Class.

    Any specific reason for using the Su 24 in Syria? Is it because the RuAF doesn’t have enough squadrons of Su 34?

    Do you have any data to back up that claim that SVP-24 is much more precise compared to similar FCC’s on the Western planes?

    For unguided bombs in the 500 kgs class the CEP was 4m to 7m from a delivery altitude of 5000m

    How can ECM stop any other plane equipped with a targeting system from doing the same?

    I didn’t say the plane. I said ECM can affect the guidance and homing systems of smart bombs. The mean deviation from target for a bomb delivered using SVP 24 is a lot lower compared to any Western analogue of a SVP 24.

    Useful in circumventing ECM? How so?

    ECM cannot fully prevent SVP-24 from computing the relative position of the carrying aircraft in respect to the intended target for precision weapon delivery. In fact the system also allows the matching of positional television data (from Kaira subsystem) with an electronic map of the area. Ergo even at a slow speed the precise delivery of the bomb on the target cannot be stopped

    From a low altitude. It gets increasingly crappy with increasing drop height

    Why so? Its CEP even from 5000m is said to be around 20m. Moreover, SVP 24 is useful in circumventing enemy ECM.

    Do you think LANTIRN is better? Thanks.

    Nice piece on the SVP 24 Targeting System being used by the Su 25 in Syria

    http://vpk.name/news/143127_obekt_na_vyilet.html

    In other words by virtue of using the SVP 24 unguided bombs can be used as guided bombs.

    Is there any truth in this news published originally by Defense News that India is purchasing the Su 35?

    Russia and India to work on 5th-gen upgrade to Su-35 fighter

    Russia and India have signed an agreement to jointly develop a fifth-generation upgrade of the Su-35 Super Flanker multirole fighter, according to a report published March 8 on Virginia-based military affairs website Defense News.

    The fighter will be a fifth-generation fighter like the US Lockheed Martin F-22 Raptor and F-35 Lightning II, as opposed to the fourth-generation version of the Su-35 over which Russia and China are currently negotiating a deal.

    The Su-35 Super Flanker will be unable to compete with other “genuine” fifth-generation fighters and China does not need to get caught up in a game of one-upmanship with India and Russia, said an expert cited by China’s nationalistic tabloid Global Times.

    Defense News cited a Russian military insider as stating that Moscow and New Delhi have signed an agreement to design what Russia is calling the fifth-generation version of the Su-35 in India, which will see an Indian variant of the fighter created called the Su-35S. Sergey Chemezov, CEO of Russian state-run tech export corporation Rostec, was cited by the website as saying, “We have been negotiating and have signed the intention protocol for the Su-35…Now we are working on designing ideas for this contract and on creating a manufacturing platform for the aircraft of the fifth generation.”

    The shift from the fourth-generation Su-35, currently in service with the Russian Air Force, to the fifth-generation Su-35S will necessitate a large upgrade. The report in Defense News questioned the ability of the Su-35S to bear comparison with the F-35. An Indian Air Force official said Russia has pitched the Su-35S several times over the last six months, stating that it can replace the Indian Air Force’s MiG-21 and MiG-27 fighters, set to be retired from service in seven to eight years.

    Russia and India have already worked together on the development of a fifth-generation stealth fighter, the PAK FA T-50. The Defense News report suggested that the reason Russia has suddenly announced the development program for the stealth fighter is because they are trying to undercut France following the refusal of Paris to provide Russia with two Mistral-class amphibious assault ships. In 2012, New Delhi decided to buy 126 Dassault Rafale multirole fighters from the French company but they have been unable to reach a final agreement due to the technology transfer involved and the price. A Russian industry source cited in the report said the Su-35S will cost only US$85 million, very competitive when compared with the Rafale, and poses a threat to the deal between France and India. A report in the New Delhi-based Economic Times previously stated that India’s air force command considers the Russian fighter and the Rafale to be complementary and that the former does not replace the need for the latter.

    PMI= FGFA.

    PMI/FGFA is that the export version meant for India? Thanks.

    What? Have you heard of any lawsuit filed against any company because their CEO said their latest product is the bestest?

    But that’s not what I have said. And you have to be specific and not talk in general terms.

    Do you really really really think a CEO is going to come out and say the product they produced prior to the current product, that they are desperate to sell, is better?

    That’s not what we were told. Lockheed had said the F 22 is the stealthiest aircraft ever built. They maintained this line even when the F-35 was being produced. Now they say the F-35 is the most stealthy aircraft. Question is, if stealth is the primary factor then why use the F-22 at all?

    who exactly would be filing a lawsuit against this claim?:confused:

    USAF of course. Because they were told the F 22 is more stealthy.
