Depends on how you do it of course. My personal favorites are based on SLICE or planing cat hulls like the Jervis Bay. Whose Big Flat Top Deck means you have reasonable ability to do air ops without resorting to a Skyhook or like system (though that could be made to work too). 50 knots up to sea state 3 also makes true STOVL as a function of lost winglift on marginal postlift not quite so critical.
IMO, 'the next big step' is going to be a two-stage system.
With forward drones either self emplacing like the French Fast-Slow UAV concept. Or missile-dropped like a scattering of Silent Eye/Finder/SMACM/LAM systems via high speed cruise.
These systems will then need a comms relay platform that functions like an AEW platform to 'bridge the horizon' with either datalink or detection facilities sufficient to cue personal defenses against intelligent TBM while counter targeting onboard weapons against point targets.
5 minutes out at FastHawk/ARRMD speeds.
Without a carrier.
IMO, the parent drone may very well be a hybrid hydrogen/solar/conventional fueled LTA. With the ability (BWB) to mount some truly big fans in a fairly deepXwide fuselage whose center well has a billboard AESA mounted keel-like within it as integral structural reinforcement to a light vacuformed semi-rigid hull.
Depending on absolute up and away performance, (and to keep deckspot controllable) it may also be wise to fit scissoring/oblique or 'retractable' joined-wing (maybe with a film airfoil if not full MAW) technology which also carries all the conventional fuel for climbout/recovery, high energy, work.
The idea being that you have a system with enough power to loft the big antenna quickly above weather on conventional turbines plus liftfans. And then /stay/ using a combination of solar plus hydrogen fuel cell technology to power the avionics (day/night).
For at least 2-3 days.
If the asset is pure ISR/BMC3 then it is workable. Leaving the weapons carriers to perform strictly as trucks (recoverable or otherwise).

Would be the benefit of using an evolved 'pocket carrier' with native amphibious capability, which would fit British doctrine quite well. (space for helos/expeditionary force/ucavs/ and a great asset in peackeeping - enforcing operations/battle management? etc). I can envisage this as what the RAN will be using future LHD's for.

Well, the Marines are already there of course so it's not like this is anything new or apt to 'multimission neglect' by anybody else.
Yet I frankly expect the notion of littoral ops along with ('big amphib' or otherwise) UCW support to live and die with the Iraq war, much as it did with Vietnam. If we were serious about GWOT we would have been swarming Pakistan on the basis of shaking the bag empty as much as full and flushing UBL out of the White Mountains. Yet now the trail is so cold that he could likely get out of the country without any problems and despite what Bush says, the likelihood is /overwhelming/ that 'another President' will see an urgent need to withdraw our forces from Iraq, in 2009.
Conventional Military Force having proven to be nothing but a pie in the face way to massively increase debt.
Get rid of littoral and 'enablers' like Excalibur and RQ-8 and all the other inshore /crap/ goes right into the toilet with it. Because they can barely protect the ship from boghammer threats (forget mines) and they cannot reach far enough inshore, from -far enough out-, _quickly enough_, to keep the parent vessel safe from even the most basic of AShM. If the ship ain't safe, the SWO Daddy's can't rely on it for support. And if the ship stands out to blue, you are back to using more or less conventional systems to get to range in time to be worth it.
There -may- be a slight gap between the two for a micro-JSF (SDLF plus LC) concept that is 'just a bomber' (BUET-VS and GBU-39). But this will have to be introduced /after/ the supporting infrastructure is in place. Or the Big Deck Navy will kill it in the crib.
That said, IMO, the rising cost of naval warfare, along with the continuing need to cover areas where we simply /are not/ wanted will have smaller and smaller task groups assigned to maintain low profile monitoring (the only USN vessel within a 1,000 miles of Hainan after the EP-3E incident was supposedly a DDG).
And that can only happen if the ship is safe and the airwing is sacrificial. ADSAM will go a heckuva ways if the threat lane is a given (attack the CSA drone) and with R-CDL technology I can easily see smaller systems similar to a late model BQM-74 in performance being able to range quite deep over threat territory _and still talk back_. Ala Sea Ferret.
The question then becomes one of scale and affordability. Because if you make a huge hull on the premise of 'modular mission inserts' and then _never build the inserts_ (most especially including Arsenal Ship VLS loads) it doesn't matter how much technology changes between mission classification it's still gonna be just what it looks like: an empty box. Even as it is class costed to the ton draft rather than true capabilities.
Which is why I look at LCS and DDX and laugh my hindquarters off.
Because the first is a heavy corvette as much as a bluewater frigate (what, a ten day stock of supplies?) yet it is equally NOT a PB/PC class 'Swift boat' and so will /never/ operate cleanly inshore with all the low tech threats that can be run up against it. It is too slow, too big and too valuable to risk in even the kinds of 'pirate' games we are now playing off Somalia.
Of course the DD-X is somebody's WWI fantasy as a cruiser-class (14,000 tons!?!?) 'destroyer' with an ironclad freeboard.
In political terms the DD-X is the USN's attempt to maintain the dominance of the CVSF while acknowledging in the most expensive, least effective, fashion, the past-due arrival of the Arsenal concept.
OTOH, the LCS is Congressional Pork designed to feed naval yards as an OHP-sorta followon.
>>
For the cost of two CVF's the Brits (at a guess) could probably buy three perhaps four of these 'pocket carriers'.
>>
If I saw the world as headed towards another round of black and white polar specific nationalist political or economic climate change, I might agree.
Instead, I see something more akin to OEF AfG where 'success' was bred less upon changing the LCD status quo (raising up a nation) than the topline leadership figurehead politics and casualties were a matter of not having reporters present to acknowledge horrific indigenous losses rather than anything approaching 'minimal casualties' (for either side).
In the soundbyte world, if U.S. forces are not present to lose, then _we don't lose_.
And Iraq is likely the Tipping Point for the latter failure of a War Of Liberation type revolutionary political sea change. From which our own political will to throw the dice will never again be 'allowed' (party policy) as much as available to again risk our collective rep for a bunch of savages that bite the hand that reaches out to them.
In these conditions, limited objective/effects based ops by mercenary or indigenous forces, with or without SOF stiffening, will largely dictate the way things are played. And a DDG or Cruiser sized asset which, 100-400nm out into the deep blue, can supply /limited/ fires to support these forces 'without acknowledgement' will be more useful than a CVSF of any flavor that has no way to cover it's actions.
The key is to be able to stay stood off (maximizing the ton-mile costs for useful mission system scaling of investment = 100nm /minimum/ per 1,500 tons vessel dwt) while using _air_ to come inshore and support either the brown/white water warfighter. And at least 'spring for throwaway CAS' another 500nm or so inshore.
We certainly have the technology to make it work. Between ramjet and gel propellant systems and microdrones like Silent Eyes, it should be possible to in fact bus multiple SDB or (dumb) LOCAAS type systems with BIA for all.
Support forces in contact (assuming they don't bring their own drones to the party) with ROVER type terminals at _considerably_ greater depth with missile and separable UAV/UCAV based microsystems (strictly parsed and partitioned separation of fires from targeting). And you will successfuly knife conventional airpower right out of the picture.
>>
Just on UCAVs though. Are they secure assets? You wouldn't want jamming/cracking of communication protocols to render them useless or worse, be employed against you. Are these platforms of sufficient maturity?
>>
I think the Armed Forces failed the smell test on 'rigid uplink data security' when the whole freakin' world got to watch commercial satcomms relay of Predator video during OAF.
That said, the reality remains that microwave systems are both directional and exceptionally powerful for their size while a 'reporting system' (GPS) could work as similarly discrete up-only overhead relay to ensure that stealth assets could be accurately communicated with via AESA type (MP-RTIP eventually, though the present testbed is the APG-77) operating at close to maximum LOS ranges with upwards of 540mbps or 1gbps on-receive.
The big question then becomes whether the drones themselves have enough oomph to talk back or if you have to significantly push forward the relay platform and put it at somewhat higher risk.
In terms of overall security, there are four basic principles to remember:
1. Flash Light to Klieg Lamp to Silent Running to ELS Hunter.
As stated above, anything Ali Babba and his band of thieves can bring in by camelback will likely never come close to being able to outyell an F-22 with upwards of 100KW worth of directional comm-strobe. Especially if, 'absent Tamara' they cannot localize against the ether the microreturn signal that is a stealthy UCAV dropping GBU-39 bombs on them, 20 miles away.
If you are fighting China, you put in a preselected target list and/or a BIA capable set of optical targeting algorithms and simply bomb a list of fixed targets while running dumb.
If you have an ability to HOJ triangulate, you drop on the emitters. Anything below the horizon without a 'commandos here' geocoordinate exclusion zone should be fair game.
2. Multichannel Spread Spectrum.
100Hz ((RRR)()DSAKLSJ@)($*(FSLFLKALR_)@)$)(OFISLRJWOWFOSFJI)
200Hz SFSFSR#$T)PFOFLKSR_))_@$)_P_FOFSL:F:LSF::LSLSLF:RK@)$FPSLF
300Hz ADSIFIOE)_R(SF()GLKF)@$EKLFKL)@$))_)F)SF@$FFGSDGALE$#RSF
400Hz A)((E(SF()(FFDIOSF_%#T(UFIOGE_)(%#((*G(G*)SG(SG)(G)()(SGT(G
Say that the above is digital pseudo random noise separated by 'channel steps' within X-Band. Assume that these are all transmitting simultaneously out of the same aperture. Realize that in the time it takes you to see it and wetware process the letter shapes, all four lines have been sent. Several times. Ignoring synchup and a few other variables which are somewhat predictable, can you find a single go-code 'APPLE' in there? Can you do it in realtime without knowing what sequence point in each crypt had -any- useful data. Or if it had two or three or none or all?
3. Single Use Keypad Crypting.
Imagine a vocabulary in which any 20 words might mean the same thing. Once. And never mean that thing again, for ten million repetitions. So that /even if/ you could find 'APPLE' in the noise, you couldn't figure out that it meant 'fly to Waypoint X and bomb target 22 on your frag list' from observed behavior. And that furthermore, the total vocabulary was so broad that nothing you ever overheard spoken would ever have the same meaning to upwards of 100 other users on the same net. For an equal period of term-reuse. That furthermore, for ALL drones, whether shot down or RTB successful, the list of code words would change for the very next DTM upload of mission orders. Now realize that the part of the drone which knows which command to associate with which code is NOT the part that is connected to the transmitter system and so effectively cannot be convinced to do a datadump of the total command list, even if it 'wanted to'. Nor can a drone combat controller. Because when he says 'go to target 22 and drop four bombs on it' he himself doesn't see 'APPLE' as a word, only his desired command before machine translation.
Takes 90% of the fun out of technical espionage to know that you are trying to talk two 10ft tall deaf mute morons out of the keys to the kingdom when they can only do sign language to each other and forget what they said after each and every communication.
4. Moated Systems, Hardwire Laws.
Milspec equivalents to Faraday Cages and metallic EMI shielding on cables and the like protect both avionics boxes and ports. Furthermore, it is possible to create datafunnels and physical or electronic 'moats' whose one-way passage or restricted (time:space) access means that if a UCAV was outside a given battlespace it simply would 'pull the plug' to the weapons system and not -itself- be able to 'recertify' until a ground crewman reset the inertial clock. Of course there would be tactical modifiers as well in that a UCAV which came in through any but a channelized passage corridor in a given period could and would be treated as malfunctioning and if it did not acknowledge a go-to-range-safing-zone recovery command, _hostile_.
Taken together, I would not say it is impossible for a Drone to be tampered with in flight. But I would say this-
A UCAVs electronic systems are no more vulnerable or less mission critical than a manned platforms.
A manned platform is typically vastly easier to detect as a preexistent requirement to /pointing/ a spoofer/meaconing system at.
Anything which rises above the horizon is looking at being fried 'quite ordinarily' by laser light much past 2015. Out to 25km from a surface site. And 60-100km using a relay mirror balloons under optimum conditions. For but a few thousand dollars per shot.
I worry about the hard kill much more than the soft one. Because I can erect barriers to subversion of the machine without ever endangering a man. OTOH, if I cannot do anything but send men over the top to slog away into the photon bullets of a 'light machine gun', my manned force has suddenly become a kamikaze one.
And that is beyond redemption as a value-in:risk out investment.
