Time notes
- 1:04CVA-01 cancellation and the advice reaching ministersNotable Point
The cancellation of CVA-01 raises a question about how ministers assess defence spending and whose advice shapes their decisions.
- 2:14Aircraft range versus persistent fleet air coverNotable Point
A range map leaves unanswered how quickly land-based aircraft can reach a fleet and how many are needed to keep fighters overhead.
- 4:28Carrier air cover protects the anti-submarine forceNotable Point
Carrier cancellation also removes the helicopter concentration, reconnaissance interception and early warning on which fleet operations depend.
- 5:43Cutting both carriers and their proposed alternativeNotable Point
The cancellation argument ends with both services losing capabilities and Britain relying more heavily on allies beyond Europe.
- 6:58Defence spending and the cost of losing capabilityNotable Point
The budget critique accepts the need for postwar reform while tracing declining independence to decisions made before the Cold War ended.
- 9:52Why Britain still needed the Invincible classNotable Point
Aircraft identification and NATO anti-submarine commitments expose the capabilities Britain still needed after cancelling its fleet carriers.
- 12:34Invincible machinery, endurance and crewNotable Point
The historical Invincible design combines redundant gas-turbine machinery with a crew of roughly a thousand people including its aviation personnel.
- 14:14Invincible sensors and submarine defenceNotable Point
Invincible's radar and sonar fit reflects the Royal Navy's concern about submarine attack.
- 15:14Sea Dart, Goalkeeper and Phalanx on InvincibleNotable Point
Goalkeeper's capabilities and Phalanx's wider adoption create different reasons to favour each close-in defence system.
- 16:00Tailoring Invincible's air groupNotable Point
Invincible's small flight deck supports different mixes of fighters, anti-submarine helicopters and airborne early warning aircraft.
- 17:06Deck-edge lifts and the Royal Navy's protected hangarsNotable Point
Larger carrier options raise questions about lifts, stability and protecting parked aircraft from heavy seas.
- 19:01Why Australia and Canada needed more aviation capacityNotable Point
An Invincible replacement had to justify itself against the task-group roles Australia and Canada expected their carriers to perform.
- 22:01Light carriers and middle-power independenceNotable Point
For Australia and Canada, carrier aviation offered task-group leadership and a stronger voice in allied operations.
- 25:18V/STOL aircraft and catapult airframe loadsNotable Point
The Sea Harrier made a short carrier deck useful while avoiding the launch and recovery loads imposed by catapults and arresting gear.
- 28:17Sea Harrier capability within procurement constraintsNotable Point
Sea Harrier supplied a useful air-defence and strike capability within political limits on rebuilding conventional carrier aviation.
- 30:11Gun ammunition, RAM missiles and the cost of close defenceNotable Point
An illustrative ammunition-cost comparison supports retaining guns alongside missile defences.
- 31:34Layered air defence and different gun rangesNotable Point
Different gun ranges and fighter cover gave fleets overlapping defences, including a way to engage aircraft circling beyond American 5-inch/38 range.
- 33:33Helicopter early warning and the Falklands funding decisionNotable Point
Previously completed research allowed helicopter airborne early warning to enter service quickly during the Falklands War.
- 34:41Choosing a carrier air group for its intended jobsChapter
Sea Kings and Sea Harriers illustrate why procurement needs to account for a navy's missions and existing capability gaps.
- 37:11Gorshkov and Soviet ocean-going naval powerNotable Point
Kirov and Kiev entered service during Soviet naval expansion under Sergey Gorshkov.
- 39:14Soviet deployments and the cost of diverting NATO forcesNotable Point
A distant Soviet surface deployment could draw submarines or a carrier group away from the main North Atlantic and North Pacific campaigns.
- 40:59Surface raiders and diversion from a decisive theatreNotable Point
German raiding operations illustrate how a threat overseas can draw an opponent's scarce major warships away from a critical front.
- 43:17Combining Soviet surface raiders with submarinesNotable Point
A feasible Soviet raiding option creates a planning problem even when the allies cannot be certain it will be used.
- 48:27The counterfactual decision to defend Atlantic reinforcementsChapter
The enlarged-carrier scenario begins with Britain preparing for a sustained war and protecting the reinforcement traffic needed to fight it.
- 50:38Sea Eagle missiles and a larger Sea Harrier strikeNotable Point
Sea Eagle's guidance and warhead support the proposed anti-ship role, while the chance of overwhelming Soviet defences remains uncertain.
- 52:46Submarine pursuit cannot guarantee a timely interceptionNotable Point
A submarine waiting in position has different advantages from one racing to catch a fast-moving surface ship.
- 55:26Prewar submarine deployments and bastion barriersNotable Point
A barrier intended to intercept submarines at the outbreak of war faces a different problem if they sail before hostilities begin.
- 56:43The maximum Invincible hull and propulsion arrangementChapter
The hypothetical enlargement approaches Kiev in scale, with additional gas turbines and fuel capacity supporting a larger carrier.
- 57:37Crewing and self-defence for the enlarged carrierNotable Point
Restrained crewing estimates accompany an enlarged carrier that retains the Invincible family's sensors and adds Sea Wolf.
- 58:41The enlarged carrier's baseline air groupNotable Point
The conservative proposal provides 24 fighters and more space for anti-submarine and early warning helicopters.
- 59:35Sustaining a fighter patrol and airborne early warningChapter
A larger Sea Harrier force supports a continuous four-aircraft patrol while keeping replacements ready and allowing for maintenance.
- 1:01:12A larger air group for sea controlChapter
Additional aircraft and deck parking could give the enlarged carrier a stronger sea-control force with limited strike capability.
- 1:02:51A longer flight deck improves Harrier operationsNotable Point
The proposed 255-metre hull provides more takeoff distance and room to consider rolling landings.
- 1:04:08Launching a rapid anti-shipping strikeChapter
Six strike-configured Sea Harriers and four covering fighters form a small anti-shipping package suited to rapid ski-jump launches.
- 1:06:22Damage can end a surface raider's freedomNotable Point
Graf Spee illustrates how damage constrains a raider without repair facilities, spare parts or a secure destination.
- 1:08:09Eight carriers change Sea Harrier productionNotable Point
A joint carrier fleet requires a much larger Sea Harrier purchase once national training and maintenance needs are included.
- 1:08:44Maritime trade and the need to protect sea routesChapter
Canada's and Australia's reasons for operating carriers rest on their dependence on trade routes and maritime communications.
- 1:11:20A multinational market for helicopter early warningChapter
Orders from several navies could bring helicopter early warning into service earlier and support continued development.
- 1:14:18More aircraft allow a stronger alert forceNotable Point
Thirty-two fighters and six early warning helicopters give the enlarged carrier more options for simultaneous patrols and strikes.
- 1:15:30Interchangeable helicopter mission equipmentNotable Point
A larger helicopter fleet raises the possibility of reinforcing early warning by exchanging mission equipment aboard anti-submarine airframes.
- 1:16:25Why larger carriers might not prevent the Falklands WarNotable Point
Carrier delivery dates and diplomatic decisions leave room for war even with a larger British fleet on order.
- 1:17:31More Sea Harriers could reduce Falklands lossesChapter
A larger fighter force with early warning could sustain more patrols and help preserve ships and supplies needed ashore.
- 1:20:59Early warning changes the Argentine fuel problemNotable Point
Helicopters north and south of the Falklands could force attackers into less efficient approaches and reduce their operating options.
- 1:22:12Export prospects for the enlarged InvincibleNotable Point
The enlarged Invincible remains smaller than Queen Elizabeth while offering a possible shared design for several navies.
- 1:23:42The infrastructure cost of CATOBAR independenceChapter
Choosing catapults requires a support system whose cost and political dependencies extend beyond the carrier.
- 1:25:18Australia and Japan could extend the joint programmeNotable Point
Greater concern for trade-route security could encourage additional carriers and a Japanese route into Sea Harrier operations.
- 1:26:49Joint procurement and carriers for the F-35BChapter
Continuing international participation could change replacement-carrier numbers, construction arrangements and practical independence.
