Dear durk-ga,
A Carrier Onboard Delivery aircraft (COD) is currently under
development, testing and operational evaluation for all four US armed
forces. It is called the Bell/Boeing V-22 Osprey and can be stored on
an aircraft carrier.
Full specifications and photographs appear on this site.

?The V-22 is a tiltrotor aircraft, combining the speed and range of
fixed wing aircraft with the vertical flight performance of a
helicopter. With its engine nacelles and rotors in vertical position,
it can take off, land and hover like a helicopter, but once airborne,
its engine nacelles can be rotated to convert the aircraft to a
turboprop airplane capable of high-speed, high-altitude flight. This
combination allows the V-22 to fill an operational niche no other
aircraft can approach. It can carry 24 combat troops, or up to 20,000
pounds of internal or external cargo, at twice the speed of a
helicopter. It includes cross-coupled transmissions so either engine
can power the rotors if one engine fails. The rotors can fold and the
wing rotates so the aircraft can be stored onboard an aircraft
carrier.?

?-The V-22 has difficulty remaining parked on rolling aircraft carrier
or assault ship decks. Correction: This is not true. Initially there
was a problem with the parking brake when the aircraft were moved on
deck because the brake rider in the cockpit needed improvement. This
fix was made in three of the four aircraft that were used during the
recently completed Operational Evaluation and in all production
aircraft since.?

Dear durk-ga,
Sorry about the misunderstanding. There has been attempts to produce
a jet VTOL cargo aircraft but none have entered operational service.
They have either failed in trials or their cargo load carrying
capacity has been so reduced that they badly under-perform against
existing cargo aircraft.
The Germans did produce one which meets your requirement: the Dornier DO 31 E.
Dornier DO 31 E - Tactical Transport VTOL Aircraft, Germany, 1967
?The Do 31 was designed as a tactical transport aircraft with VTOL
capabilities. The construction did work, but the project was grounded
later.?
http://www.luftfahrtmuseum.com/htmi/itf/do31e.htm
There is a photograph on this page.
?The aircraft in the photo is a Dornier Do 31 E. The photo was taken
at the Duetches Museum in Munich.
At the time it was the largest V\Stol aircraft, being a transport type
designed to carry 36 troops, 24 litters, vehicles or cargo.
The 1st flight took place on 10\2\67 and the first transition from
vertical to fwd flight on 16\12\67.
Each wing tip pod accomodated 4 x 4400 lb thrust RR RB.162-4D engines
for vertical thrust. Fwd thrust was provided by 2 x Pegasus turbofans,
which could also be vectored for vertical thrust.
Intitially 2 prototypes were built by Donier, VFW & Hamburger
Flugzeugbau. I cannot ascertain whether the aircraft went beyond the
developement phase .?

Detailed additional information appears on this page which is part of
a site which gives a detailed history of V/STOL aircraft. You may find
it of interest.

I think the general concesus is that the future lies in H-VTOL; here is an example.

I hope this now answers your question fully,. Let me know if it does
not by way of clarification.
