Tambrian Carrier Group

EDIT, 28.08.13: I updated the image by adding tactical markings to the ships, something I forgot to put in previously.

The Tambrian Carrier "Wrath of the Guide" with two escort cruisers (the Tambrian navy uses "escort cruisers" to cover the roles held IRL by both destroyers and light cruisers) "Luminary Tal Epehti" (top -named after a Tambrian war hero) and "City of Farfal" of the "City Class" (bottom) steaming at a leisurely 12 kts through the waters of the Outer Ocean.

The carrier is currently both launching and recovering aircraft for a routine patrol over the Marban/Tambr border area.
You can see the second of the outbound fighters just separate from the rail-mounted catapult, while the inbound flight is already hooked on the landing trapeze and one of the aircraft has already been stopped.

The inner space world uses this system of overhead trapeze and hooks for aircraft launch and recovery due to this world's lack of rubber or rubber substitutes, which precludes the manufacture of practical pneumatic tires. Since the trapeze-and-hook has a practical weight limit, larger aircraft tend to be seaplanes, especially since the wast majority of people in this world live either on the coast of the shallow Inner Sea or within easy access of it.

The ships all use oil-fired steam boilers and steam turbines, while the on-board weaponry is composed of anti ship rocket mortars (in fact more akin to the M81E1 152mm gun/launcher of the M551 "Sheridan") and anti-aircraft heavy calibre cannons. The cruisers also mount a depth charge launcher near the stern and submerged torpedo tubes.
