Apollo again, how about the booster?

told today that Apollo style "capsule" would be Nasa´s new manned
spacecraft. But how to get it to the orbit?

The capsule is just one of the designs being looked at; no final decision
yet. Whatever is built, it's supposed to fit on both the Atlas V and Delta
IV.

Grazie. How big payload Atlas V or Delta IV can get to the orbit? I
mean how many seats there will be in a new "capsule"? More than 3?

I suppose those are not so powerful launch vehicles as were Saturn 1B
and Titan 3 class rockets?

I believe OSP has an explicit requirement to carry at least 4, at least in
the lifeboat configuration. However, that doesn't mean it'll be twice the
mass of a Gemini. The EELVs, especially Atlas V, have plenty of lift
capability for reasonably-designed capsules.

The Heavy configurations of the EELVs were explicitly required to roughly
match the Titan IV. However, it would be desirable for a capsule to fit
on the Medium configurations -- a bit bigger than the traditional Atlas --
and that ought not to be hard.

The smallest of the rockets a base Delta 4 can deliver 8400 kgs to ISS, this
will go up some when it gets the MB-60 second stage. The Atlas is bigger at
12,000 kgs to ISS.

The new capsule is supposed to seat 4.

Gemini carried two people and weight less then 2000 kgs times 2 would be
4000 kg but it was very small.
The British designed a 4 man with 500 kgs cargo or 8 man emergency capsule
that weighed just over 7000 kg
The Big Gemini proposal weighed 15,600 kg. It would have had an escape tower
carried 9 people and 2500 kg of cargo.
If you divide that by 2 you have 4 people and 1250 kg for about 8000 kgs.

So even the smallest can launch a 4 man capsule.

I would assume a minimum of four seats, probably more; if it is a
capsule it will be a bit larger than Apollo's reentry capsule. There
are no firm details yet.

and Titan 3 class rockets?

About the same as a Saturn IB; Atlas V and Delta IV are replacing Titan
3/4. The "Heavy" variants would probably be used as the launch vehicle,
but that will depend on the final weight of the OSP. A capsule design
might require a less powerful version.

Atlas V and Delta IV provide a range of configurations that
are, in their most powerful configurations, more powerful
than either Titan 3C or Saturn IB.

Saturn IB could boost 18.6 tons, and Titan 3C 13.1 tons,
to a 185 km x 28.5 deg orbit. During the Apollo 7 mission,
SA-205 lifted 16.53 tons to a 222 x 282 km deg orbit.

A basic Atlas V/401 can lift 12.5 tons to the same orbit.
Atlas V/552 (with five solid rocket boosters) can boost
20.5 tons into that orbit.

Delta IV-M can lift 5.4 tons to the 500 km x 51.6 deg ISS
orbit (or 8.6 tons to 185 km x 28.5 deg). With four solid
boosters it can loft 13.5 tons to ISS. Delta IV-Heavy can
boost 24 tons to ISS.

The Atlas 521 that flew this summer was actually capable
of hauling more low earth orbit payload (15.1 tons) than
Titan 3C.
