    There are two versions of the NH90 – TTH (Tactical Troop Transport) and NFH (Naval Frigate Helicopter?), a similar relationship between the UH-60 Black Hawk and Sh-60 Sea Hawk.

    The TTH NH90 are currently being delivered to both Army and Navy to replace the Sea King and Black Hawks.

    A decision is due in ~2015 on a replacement for the S-70B Seahawks. Its either the NFH or the MH-60R. If its the MH-60R the Naval NH90 will be based to the Army.

    Yep, all USN F/A-18F from Lot 32 (FY2008) have provision for conversion to EA-18G (they want provision for future expansion). They aren’t actually fully wired (the wings are), the space is left for the looms in the fuselage. There are a number of other airframes mods, and the rear cockpit is heavily modified – the EA-18G isn’t quite as common with the F/A-18F as originally planned.

    The RAAF hasn’t made a decision on the EA-18G and isn’t due till the decision on the final batch of F-35 is made. Theres a number of problems – lack of ALQ-99 pods for export, export clearances for the pods, the fact that a new generation of pod/pods should replace the ALQ-99 at around the same time as RAAF EA-18G would be due.

    None are showstoppers and the upgrade isn’t hard, but it will not be cheap and it will take time.

    He also quotes the RAND Taiwan tanker scenario report as a source….

    Lynx was in competition with the S-70B back in 1980s and the Super Lynx with the SH-2G in the 1990s. S-70B are planned to retire when the FFGs go.

    Squirrel are currently training only and are planned to retire sometime after 2011.

    A109 are an interim type, due to the failure of the SH-2G – the three are under lease.

    The first of the six naval NH90 transport aren’t due to deploy till mid 2010 to replace the Sea King.

    So in 10 years time or so, it will be 6 transport NH90 and either ~24 MH-60R or naval NH90, with another training type.

    I’m too lazy at the moment to do the math, but if we go with 6.7 lbs per USG:

    900 USG/minute is 6030 lbs/minute
    1200 USG/minute is 8040 lbs/minute

    Annex ZE gives the following for the KC-135/KC-10 max transfer rates (lbs/minute):
    B-1B: 7000/7000
    B-52H: 6500/7300
    C-5: 6800/7300
    C-17: 6800/8400
    KC-10: 6500/7800

    Any idea on the revised RFP transfer rate?

    Tu-95MS has the Meteor-NM EW suite. This includes MAWS, SPS-100 Geran jammer, RWR and decoys.

    The suite was found to effective against the MiG-31 during exercises.

    I must admit I’d be interested to see what a/c in the US inventory can receive fuel at such high rates of flow. 1200 gals does seem a quantam leap.

    Check out: http://www.raf.mod.uk/downloads/airtoair56b.cfm

    Specifically this one Annex ZE towards the bottom of the page: http://www.raf.mod.uk/downloads/atp56usnationalannex.cfm

    I’m fairly sure the rates they give are lbs/minute, and I am unsure how to convert these to USG or litres of EADS Kood-Aid….

    And page 37:
    “Much of the information in this paragraph comes from Carlo Kopp and his Airpower Australia website, an amazing, deep source of up-to-date….”

    Kopp’s site does have some interesting pieces of information, but he has stuffs up when he tries to put the pieces together.

    No its either or.

    1) Retain and upgrade the F/A-18F and maybe 12 to EA-18G.

    or

    2) Retire the F/A-18F and purchase the additional F-35A.

    Back in the day (1991) the RAN deployed two FFGs (HMAS Adelaide, HMAS Darwin) and a tanker (HMAS Success) to the Gulf region. It was a meaningful and worthwhile contribution. This was then replaced by HMAS Sydney, HMAS Brisbane and HMAS Westralia. With the amount of shipping spread over such a wide area (Persian Gulf, Gulf of Oman, Red Sea, etc), you can never have too many tankers.

    Its as much about making a meaningful contribution as opposed to always having to lean on our allies. HMAS Success shuttled from the main carrier groups to the forward ships.

    Found my notes on the pre-HMAS Sirius proposal. Two (2009, 2015) around 8250 light, 10000 t fuel, 1300-1500 t JP-5, 100 t stores, 250 t ammo, <100 crew (no jackstays – all stores by helo). Either one or two Sea King. And a reduced acoustic signature for the reasons already given.

    HMAS Sirius was a compromise with around 50% the costs of the new class. She lacks a dedicated hanger and onboard helicopter maintenance facilities, In any case she is due to replaced 2018-2020 (entered service in October 2006).

    In peacetime ships need fuel to outrun storms, SUBSINK or for long range rescue operations, in war the tanker might be sunk by enemy action – ships are constantly topping up fuel. Theres a certain percentage of fuel that RAN ships had to enter port with – otherwise Naval Command had to be informed by signal. Tankers result in more time at sea on station and on task.

    Not sure where I got these figures from , but the F-22 environmental system is cleared to 66000 feet (20,064 m).

    With full military power the F-22 can hit 50,000 feet (15200 m), reheat gives 65,000 feet (19760 m).

    ‘Typical operating altitude’ is 60,000 feet (18240 m).

    When were the helmet mounted displays declared operational?

    Fort Victoria class were also to have been fitted with the DNA combat system, Type 996 radar and 32 VL Seawolf with two Type 911 directors – all were cancelled due to $$$$$.

    Not sure on reduced signatures. The Wave class has reduced radar signature from sloped superstructure and RAS kingposts.

    Whatever the new RAN AOR it needs to have substantial cargo/stores capability, and additional aviation facilities wouldn’t hurt.

    SPS-49 is a little out of date, especially by the 2020s. It would need a long range search radar, part of any future RAN escort requirement is long range patrol.

    Maybe SMART-L?

    F-35B bring back was given as 2240 kg with 5 minutes hover. The proposed rolling landing would add 1000 kg.

    F-35C bring back is 4536 kg, also given as 4310 kg and 4082 kg (2268 kg weapons).

    F-14D is 4082 kg with 1360 kg fuel/2722 kg weapons day and 1815 kg fuel /2267 kg weapons night.

    F/A-18C is 2495 kg in the tropics, due to the need for reserve fuel for a couple of missed approaches – 1135 kg of weapons can be recovered during the day and 680 kg at night. During 2003 bring back was effectively a single GBU-31 equivalent. Also given as 1800 kg of fuel and 700 kg weapons.

    F/A-18E is 4490 kg, F/A-18F is 4082 kg including 2200 kg weapons
