Wendover Productions - Cities at Sea: How Aircraft Carriers Work

Short Summary

Main recommendation: No single recommendation; the video explains how modern aircraft carriers operate as self-sufficient floating cities and why they remain strategically important despite their vulnerability. It covers their strike-group protection, resupply at sea, aircraft launch and recovery, crew organization, and the US use of carriers for power projection. The video also notes that carriers have never actually been sunk in war games, but submarines have gotten close enough in simulations to have theoretically sunk them.

Key Points

• Under international law, aircraft carriers can position themselves up to 14 miles (22 km) from any country's coast, and 80% of the world's population lives within 60 miles (100 km) of the ocean.
• Only 19 carriers worldwide can launch fixed-wing aircraft; China, Thailand, India, Russia, and France each have one, Italy has two, and the US has the eleven largest, each needing over 6,000 people and often deploying for up to a year.
• Carriers never travel alone; a typical US strike group includes a guided missile cruiser, two guided missile destroyers, an attack submarine, and a supply ship, with the carrier serving as flagship.
• Nuclear-powered US and French carriers can sail an unlimited distance for about 25 years without refueling, but food and aviation fuel limit them to a few weeks at sea, so they resupply underway.
• Carriers use catapults or arrestor wires to launch and recover aircraft in very short decks, and US carriers have "airport at sea" logistics via C-2 Greyhound cargo aircraft.

Details Worth Noting

• Concrete instructions: At sea resupply works as follows: the supply ship sails to a nearby port for fuel, ammunition, food, and mail, returns, matches speed alongside the carrier, and fires lines across. Lines pull hoses for aviation fuel transfer. Solid supplies move either by pallets on dollies running along a line like a zipline, or by helicopters lifting pallets from the supply ship to the carrier. Expedited US mail to a deployed carrier can arrive in about ten days.
• Flight deck crews are identified by shirt color: yellow directs aircraft, blue assists yellow, red handles ammunition, purple fuels aircraft, green covers catapult, maintenance and cargo crews, white covers landing aids and medical, and brown plane captains oversee aircraft readiness.
• A large carrier carries up to 100 aircraft, moved between flight deck and hangar by elevators. The US Gerald R. Ford is 1,106 ft (337 m) long, and aircraft take off within about 325 ft (99 m) using catapults.
• Enlisted personnel typically get a single bunk, sometimes in rooms with more than a hundred others. Carriers can reach the Middle East from Norfolk in about a week, and the USS Ronald Reagan could reach North Korea's shore from Japan in about 29 hours.
• In war games, Swedish (2005) and French (2015) submarines "won" against US carriers by getting close enough to potentially launch torpedoes.

Bottom Line

Aircraft carriers are massive, costly, and vulnerable, yet they remain a powerful tool for projecting military influence worldwide, which is why countries keep building them.
