First of all you could try to get your argument straight. MRH-90 was an Army managed project with a limited RAN involvement whereas Seasprite was a solely RAN managed project. So which user are you pointing the finger at exactly? Or are you just blaming all of Australia for that? All 3 services are exactly the ‘same’ in terms of inventory management and sustainment are they? Lol.But, you do, and you are, kinda the whole point.
The seasprites didn't enter Australian service because Australia canned the project all together after years of trying and billions of dollars, again that was an Australian call not Kamans. The US had been using seasprites for decades and the RNZAF are using them now, funnily enough the exact same ones even, and you are still trying to say it's the type?? Seriously? Your claim would make some kind of sense if no one was using them before and the fact that someone is using them now is only further de-bunking your myth.
Secondly, your figures are wrong. The entire SeaSprite project expenditure was $1.1b not “billions”.
Thirdly the SeaSprite capability RAN tried to introduce is not one either the RNZAF or the USN ever operated. We attempted to introduce a bespoke 2 person crew design, utilising advanced avionics and equipment to replace the 3rd crewman. The airframes subsequently sold to NZ were de-modified and reverted back to the original 3x crew configuration. The SH-2G(A) standard is not the standard RNZAF flies and wisely has never tried to.
The problems with SeaSprite however are entirely different to the MRH-90. The problem was the basic design of the SH-2G(A). RAN started with an illogical design idea - take a 3 person helicopter and try to use automation and “advanced” avionics ( from the 1990’s…) to turn the SH-2G into a 2 person helicopter and do the same job. Despite it never working they persevered futilely until a smart enough Government cancelled the whole thing and ordered the aircraft they should have invested in originally.
The MRH-90 fleet however has never lived up to expectations in terms of cost, availability or capability. The basic design concept isn’t the problem as it was with SeaSprite. The entire fleet (plus 1 extra aircraft provided by Airbus helicopters due to contract penalties for non-performance no less…) was in-service and Army and RAN worked with the manufacturer for decades trying to get the things to deliver what they promised.
The problems with NH-90 as a fleet is the problem that has led to us cancelling them and as it happens is one not unique to Australia, as has clearly been demonstrated by other users, all of whom ran bigger fleets of same than NZ does.
The only ‘commonality’ between both situations is ADF choosing the wrong capability and trying doggedly despite that to make it work, in both cases, ultimately unsuccessfully and being let down ultimately by manufacturers who couldn’t deliver what they were contracted to do.
Directly from Army evidence on oath to the Australian Senate,RNZAF was the first user in the world to reach 2000 hours on the NH90 and has one of the best availability rates bar none so not sure where you are getting your info from re Australia? A major excuse is your low availability rates for the type so how does that then equate to flying them "more" than anyone else, including RNZAF?? Are you comparing the flight hours to date combined of all 47 ADF 90s to the single NZ 90 with 2000 hours? Ironically if you had flown the type more then obviously your availability rates would be comensurate or are you suggesting users like RNZAF have hit the 2000 hour mark and then parked up their fleets?
No I am not, I am comparing overall fleet hour numbers, One RNZAF aircraft may have reached 2000hrs, but the Australian fleet as a whole has flown well beyond 40,000hrs and it’s overall fleet hours useage substantially exceeds the hours accrued by any other user.
Tiger has some of those problems it is true, but Army is fairly happy with it’s availability now - that isn’t the reason it is being replaced. It is being replaced because they believe the capability is obsolete. Australia as a participating OCCAR member and a long time user is well aware of the capability of the helicopter and aware of the requirement for it needing to be substantially upgraded and has expressed reservations about the ultimate capability they can get out of it.You are replacing the tiger early as well due to "similar problems" so no, I wouldn't exactly consider that any kind of success story, at all. You would only like to hope 4 out of 7 types of helicopter fleets in service work otherwise it would really be a difficult to overlook and not entirely sure how you can't blame poor management on the user with those kinds of stats!
This lack of capability is recognised by others in the program with Germany also deciding to phase them out (in favour of the H145M no less) and the other users deciding the substantial Tiger Mk3 upgrade is required.
Australia also has an expanded fleet requirement that Airbus helicopters is unable to fill, hence their (silly) proposed ‘dual fleet’ upgraded Tiger + H145m combo to meet our requirement, moving from 22x airframes to 29x airframes as we are with Apache.
So yeah, pretty solid argument all round…
