What material to use for a near-future armoured spaceship?

In a setting with (mostly) near future technology what material would a top end naval spaceships hull be made out of?

The hull must follow the following requirements:

• Able to withstand the strains of space travel (containing internal atmospheric pressures, radiation shielding, microscopic impacts on a ship hitting 400000mph etc)
• It doesn't need to be able to land as the ship was launched from and will remain in space throughout its life.
• Armoured from attacks of anything up to a large non-nuclear missile.
• Not required but worth bonus points: resistant to corrosive, electrical or any other weird attack you can think of.

The materials you can use are:

• Any material we have now/will probably have in the next 30-50 years. There is a lot of interstellar trade so most raw materials are available and the navy is willing to pump in a lot of funds so cost is no barrier.
• The hull can be made of more than one material if you think this would be a better option.
