1. Strategic Reach at Sea
   The FAA gave the Royal Navy the ability to project air power independently of land bases. This was crucial for protecting convoys, raiding enemy shipping, and extending reconnaissance range. Britain’s global commitments required this flexibility.

2. Pioneering Carrier Operations

   • The FAA was among the first to show how aircraft carriers could dominate naval engagements.

   • The attack on the Italian fleet at Taranto (1940)—using Swordfish biplanes—crippled several battleships and directly influenced Japanese thinking ahead of Pearl Harbor.

3. Contribution to the Battle of the Atlantic

   • FAA aircraft escorted convoys, hunting U-boats with depth charges and rockets.

   • The introduction of escort carriers (small carriers converted from merchant hulls) was particularly effective in closing the “mid-Atlantic gap” where German submarines had previously been safe.

4. Arctic, Mediterranean, and Pacific Campaigns

   • In the Arctic convoys, the FAA provided fighter cover and strike capability against German forces in Norway.

   • In the Mediterranean, they supported Malta convoys, engaged the Italian Navy, and struck Rommel’s supply lines in North Africa.

   • In the Pacific, the British Pacific Fleet deployed modern carriers alongside the US Navy, fielding Seafires, Hellcats, and Barracudas.

5. Technological and Tactical Adaptability

   • Despite early disadvantages (obsolete aircraft like the Swordfish), the FAA quickly adopted more modern aircraft (Martlets/Wildcats, Corsairs, Avengers).

   • Their pilots developed low-level torpedo attack tactics, night operations, and shipborne fighter direction (primitive airborne radar).

6. Global Scale

   • FAA squadrons fought in the Atlantic, Mediterranean, Indian Ocean, and Pacific, reflecting Britain’s worldwide naval commitments.

List of Royal Navy Aircraft Carriers in WW2

The FAA operated from a wide range of carriers, from fleet carriers to smaller escort carriers. Below is a comprehensive list of UK carriers that saw service in WW2:

Fleet Carriers

• HMS Courageous (sunk 1939)

• HMS Glorious (sunk 1940)

• HMS Ark Royal (1937, sunk 1941)

• HMS Eagle (sunk 1942)

• HMS Furious

• HMS Hermes (sunk 1942)

• HMS Illustrious

• HMS Formidable

• HMS Victorious

• HMS Indomitable

• HMS Indefatigable

• HMS Implacable

Light Fleet Carriers (introduced 1943–45)

• HMS Colossus

• HMS Glory

• HMS Ocean

• HMS Venerable

• HMS Theseus

• HMS Triumph

• HMS Warrior

Escort Carriers (converted merchant ships, vital for convoy protection)

• HMS Audacity (first RN escort carrier, sunk 1941)

• HMS Activity

• HMS Archer

• HMS Attacker

• HMS Battler

• HMS Biter

• HMS Campania

• HMS Chaser

• HMS Dasher (lost 1943)

• HMS Emperor

• HMS Fencer

• HMS HMS Nabob (damaged 1944, Canadian-manned)

• HMS Patroller

• HMS Pursuer

• HMS Searcher

• HMS Speaker

• HMS Tracker

• HMS Trumpeter

• HMS Vindex

(Many of these were built in the USA under Lend-Lease and transferred to the RN.)

✅ In summary:
The Fleet Air Arm allowed the Royal Navy to wage war on a truly global scale. It struck at enemy fleets (Taranto), defended lifeline convoys, pioneered carrier aviation tactics, and fought alongside the US Navy in the Pacific. Though starting with outdated aircraft and limited carriers, by 1945 the FAA was a first-rate naval air force with modern ships and planes.

​

Here’s a structured timeline of the Fleet Air Arm (FAA) in WW2 (1939–1945) showing how its role evolved from early improvisation to global power projection:

​

1939 – Outbreak of War

• September – FAA formally transferred from the Royal Air Force back to Admiralty control (just in time for war).

• FAA strength: ~230 operational aircraft, many obsolete (Swordfish biplanes, Skua dive bombers).

• HMS Courageous sunk by U-29 while on anti-submarine patrol (17 Sept), showing the vulnerability of carriers.

• ​

1940 – Norway and the Mediterranean

• April–June – Norwegian Campaign: FAA aircraft from HMS Ark Royal and Glorious conduct strikes and reconnaissance. Glorious sunk by German battlecruisers Scharnhorst and Gneisenau.

• July – Attack on Mers-el-Kébir: FAA provides spotting for the RN attack on the French fleet.

• November – Battle of Taranto: Swordfish from HMS Illustrious cripple Italian battleships with the first all-aircraft carrier strike in history.

• ​

1941 – Expansion of Carrier Strikes

• May – FAA aircraft from HMS Victorious take part in the hunt for the Bismarck, scoring a torpedo hit that helped slow her before final destruction.

• Malta Convoys – FAA defends supply runs to Malta, fighting Italian and German aircraft.

• Escort carriers introduced (HMS Audacity), providing convoy air cover in the Atlantic.

• November – HMS Ark Royal sunk by U-81 after flying off Malta convoy fighters.

• ​

1942 – Heavy Losses and New Theatres

• April – Indian Ocean Raid: FAA suffers losses as Japanese carriers strike Colombo and Trincomalee. HMS Hermes sunk.

• May – Madagascar Campaign: FAA supports British landings against Vichy French forces.

• August – Malta Convoy Operations (Pedestal): FAA provides crucial cover, though HMS Eagle is lost.

• Escort carriers increasingly used in the Atlantic against U-boats.

• ​

1943 – The Turning Point

• Escort carriers (Biter, Archer, Tracker, Vindex, etc.) help close the mid-Atlantic “air gap,” providing continuous air cover for convoys.

• FAA aircraft begin carrying rockets and depth charges against U-boats, achieving significant successes.

• Mediterranean: FAA supports landings in Sicily (Operation Husky) and Italy (Operation Avalanche).

• FAA starts re-equipping with American-built fighters (Martlet/Wildcat, Hellcat, Corsair) and bombers (Avenger).

• ​

1944 – Global Reach

• April – Strike on German battleship Tirpitz (Operation Tungsten): Barracuda dive-bombers damage her in Norwegian fjords.

• June – D-Day landings: FAA carriers provide air support and anti-submarine patrols.

• July–August – More FAA strikes against Tirpitz (Operations Mascot and Goodwood).

• September – FAA participates in Aegean operations against German garrisons.

• Pacific Theatre: The British Pacific Fleet formed with fleet carriers (Illustrious, Indomitable, Victorious, Indefatigable) and light fleet carriers (Colossus, Glory, Venerable, etc.).

• ​

1945 – The British Pacific Fleet

• FAA now fields modern aircraft (Corsair, Hellcat, Avenger, Seafire).

• January–July – FAA carriers operate with the US Navy, striking Japanese bases in Sumatra, Okinawa, Formosa, and the Japanese home islands.

• FAA pilots engage in large-scale air battles with the Japanese and contribute to the neutralisation of kamikaze attacks.

• August – FAA aircraft carry out final strikes before Japan’s surrender.

• ​

Summary of Evolution

• 1939–40: Small force, obsolete planes, pioneering strikes (Taranto).

• 1941–42: Costly losses but expansion of escort carrier role, defending convoys.

• 1943: Technological and tactical maturity; FAA closes Atlantic gap and supports Mediterranean landings.

• 1944–45: Modern carrier force with global reach, working alongside the US Navy in the Pacific as a first-rate naval air arm.
