Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India's new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 55,000t-65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at around 22,000t. HMS Invincible actually compares well to Italy's new Cavour Class (27,000t), and Spain's Principe de Asturias Class (17,000t). The USA's Nimitz Class and CVN-21, in contrast, fall in the 90,000t-105,000t range. Hence the unofficial designation "super-carriers". Just one of these ships packs a more potent air force than many nations.

The USA isn't resting on its laurels, however; the new CVN-21 Class will resemble the Nimitz Class super-carriers in size, but a slew of changes and new technologies are promising improved operational effectiveness, substantial efficiency savings, and future upgrade potential. Along those lines, Raytheon passed a recent systems requirements review (SRR) for the CVN-21 Class' electronics. They're the industry lead for integration of all government furnished combat systems, C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance) and aviation support systems.
This is just one of the new items to be found in DID's upgraded and revised CVN-21 briefing, which includes detailed information about the ship class' key improvements, updated news and contract awards under the program, more information about the transition ship CVN 77 USS George H.W. Bush - and one blast from the past. Read DID CVN-21 focus briefing: "Design & Preparations Continue for the USA's New CVN-21 Super-Carrier (updated)."
Tomorrow, DID will delve into some discussions we've been having with NAVSEA re: the CVN-21 program's costing, and go into more detail re: proposed future savings.
That's "Queen Elizabeth", BTW
Yup, hit the adjacent key by mistake and didn't notice. Thanks.
Many of the other carriers don't have an angled landing deck. Is it because they are too small or do they specialize in V/STOL aircraft and choppers?
Yes to both.
Angled decks tend to go with catapult launched naval fighters, not V/STOL or STOVL. The French Charles De Gaulle class has them, for instance, because it's large enough (40,000t+) and flies Rafale M and Super Etendard fighters. Catapult launches take more prep, so having two speeds things up a lot.
Invincible, with its handful of Harriers, doesn't need that and really isn't big enough to make it worthwhile.
The USA's LHD Wasp Class amphibious assault ships are the size of the De Gaulle, but operate Harriers and helicopters. You guessed it - no angled flight deck.
The UK's Alliance design for their CVF is bigger still, but is only slated to operate F-35B STOVL fighters and helicopters. Click on the CVF link, and notice that there's a landing/storage are on that side, but no real angled deck.
If Britain pulls out of the JSF program, however, the catapults will be installed and watch an angled flight deck suddenly appear.
"HMS Invincible actually compares well to Italy's new Cavour Class (27,000t), and Spain's Principe de Asturias Class (17,000t)."
The only true STOL carrier is the Spanish one. Invincible is an old design . It takes less Harriers than Principe das Asturias while bigger. The Italian ship is a multimission ship prepared for troop transport also it isnt mission STOL carrier.
It has only a 134m hangar in a +200 ship.
