Thales has, allegedly, developed a lightweight Searchwater array called the 2000MS that is based on the 2000AEW set fitted to ASaC. The claim is made that this array tips the scales at 100kg.
Boeings A-160T Hummingbird UAV has demonstrated a capability to lift 1000lb’s for an 8hr stretch unrefueld and 500lb’s for 12hrs. It also has enough onboard power generation for the impressive looking Forrester radar.
We’re looking at TOSS for what reason again?.
The point is though that the RN is looking for a MASC (Maritime Airborne Surveillance & Control) aircraft. An unmanned flying radar array can’t by it’s very nature provide the control element.
Control implies having operators on board to make the instant judgements, and I’d go further an suggest that MASC should have an autonomous capability without being tied to a mothership or requiring portable base stations.
What a cheap EAGL could look like:
>> A simple but huge delta, 80x80m max dimension to stay compatible with airports, part BWB, part Burnelli, maybe with a Sea Vixen style forked tailplane.
Not designed for highspeed flight – 300kts cruise has to be enough. I think low max speed is key to fulfill the USAF requirement.
And here is also the right place to utilize strange ideas, like superstrong styrofoam or metal foam primary structure, &c. I think a non-conventional “fuselage” is another key criteria to fulfill the requirements.>> A bubble payload fairing on top, not as a load-carrying structure, only as a shell so that your stuff doesn’t get wet, kind of. Akin to Beluga.
And not pressurized – that saves a lot of weight.
Could even be built like a tent, or maybe as a pneumatic structure. When going only 300kts that could be possibe.>> The landing gear. No landing gear actually. A number of multicell air cushions along the belly, each with their own blower subsystem (take it from JSF). Landing speed of such a thing would be very low, ground effect huge, the viability of air cushion landing gears was proven in the late 60’s. Deleting the landing gear saves tonnes and tonnes of gear and structural weight.
Could turn on a dime on the air cushion. And the beauty of such a thing would be the ability to land on water.>> 4 to 6 turbofans as propulsion, like on the BWB concepts. Could be even possible with turboprops, like 8 to 12 TP400 for example. Efficiency of existing turbofans at low speeds might be sub-optimal, that’s why props. Ultra-low wingload and the lack of drag from wheels on take-off could allow for an unusually low t/w ratio.
With the huge internal volume of the wing available, things like hydrogen fuel could be looked at.
Haven’t you just described Thunderbird 2 😮
With the E-2D about to roll into production, might the most economical and wisest solution simply be to start producing a modernized version of the C-2 sharing powerplant, airframe, refueling capability and flight deck with the E-2D, similar to the fashion C-2As were again placed into production in the 1980s (a “C-2B” is you will). Especially if you consider there isn’t a market for much more than 40 or so airframes (with France, and perhaps the RN and Indian Navy as additional customers for a handful more).
I don’t see how there is much more money for development of a whole new airframe in the COD role (especially given the demands of getting off and back on a carrier).
The CVF of the Royal Navy isn’t catobar, so wouldn’t have an interest in such an aircraft
The V-22 can’t be used as basis for a carrier-borne AEW platform. To put it under deck you need to rotate the wing parallel to the fuselage – and how do you mount your radar then? For a belly mount not enough ground clearance, for a side-looking fuselage mount too much masking by the engines.
This from http://navy-matters.beedall.com/masc.htm seems to show that suc a system would be viable.
Though personally I’d have thought something like an Ericsson Erieye with a fixed rear mount between the twin tails and a pivotable front mount that still supports the Array when the wings are stowed.
Another contract announced for the 2 CVF’s, with the contract awarded to the aircraft lifts…

I think what also has to be taken into consideration is that the overall costs are for the project, and the project is essentially made up of 3 different aircraft with some commonality.
Those airframes then have to go through some common but lots of individual testing and certification.
Given that, to then break the overall costs down to $70m a unit isn’t actually that bad.
Especially if compared with the costs of 3 separate designs for the differing roles.
From:http://www.airtanker.co.uk/capability-airtransport.htm
Air Transport Capability
Modern, comfortable, fully equipped passenger cabins providing up to 290 seats with no reconfiguration of the tanker transport required
A330 standard cargo space fully available for the widest range of pallets and containers
Lower deck cargo bay equipped with semi automatic loading system
I thought these were to be based on Combi-freighters with modular passenger sections to allow the option of a full palletised cargo or Cargo/pax mix?
The drop in capability from the accident waiting to happen MR2s to P-3s is enormous.
Even the USN’s wonder toy the P8 will be less capable than the MR4A
If they are of used at all in the civilian arena I’d be surprised since I doubt the numbers would allow that much spare capacity to be sold off.
Civilian passengers I’d have thought unlikely, more likely freight if anything. Perhaps even only open to charter for humanitarian relief charities.
As for tail codes, off the top of my head the civilian owned trainers (Tutor, firefly and King Air 2000), have roundals and civilian G- registrations.
Not sure how that would work for a “front line” aircraft though
The problem with pulling the plug now, is that there isn’t an alternative with anything like the capability available “now” that can replace it. The P8 prototype/test aircraft isn’t even due to fly until next year and has an IOC (Initial Operating cpability) with the USN of 2013.
One question that I’ve lost track of in all the PFI nonsense…Are the RAF receiving new build A330s or are they second hand conversions to MRTT?
The bemusing feature of the Article was that graphic representation of an Boomed A330 refuelling a B-2, and it’s relevance to the RAF deal.
Is the Times trying to suggest that the RAF MRTT’s will have a Boom?
Hawk 200 Series … Latest Ardour Engine with Digital Cockpit.
Last sold with an APG-66H radar, wired for Sidewinder AAM, with Maverick or Brimstone as a PGM. A pair of 500lb dumb or retarded bombs under each wing.
Not in the Gripen or F16 class, but would do a job on COIN and CAS, even second layer air defence for the correct airforce.
There was talk of abandoning the EH101 and going to the much larger MH-53K.
Isn’t there a “White House Lawn” consideration, namely that the MH53 would be too big for the current parking spot.
Surely it was a case of the DOD/USN/USMC whoever made the decision that the 101 was to airframe to have, it fitted the original specification at the correct price.
The real issue is that once the airframe has been bought they are suddenly confronted with so much cabin space that they are now throwing in complex communication systems amongst other things (not in either Seaking or blackhawk) …. It’s these and issues regarding their integration that since they weren’t on the original specifications are pushing up the costs.
Had it been a Sikorsky airframe that won the contract, these issues and high costs would still be there, though perhaps slightly fewer given IIRC it has a slightly smaller cabin size
