Steel is cheap and air is free.
Basically it costs very little more and may infact cost less to build a larger hull for a given task than a small one, so long as the temtation to fill the extra space with expensive toys is resisted.
A good example of this is the ACPB (yes I know they are aluminium not steel). These are significantly larger and more capable than the vessels they replace yet on paper appear to offer little improvement.
Could the same be applied to our major surface combatants, the obvious candidate being the eventual ANZAC replacement?
A large or very large hull (8000 to 12000 tonnes) but stealthy through careful shaping of its hull and superstructure.
It would use a large commercial medium speed marine diesel boosted by gas turbines in an all electric propulsion system with stearable motor pods.
The armament would be similar to the ANZAC's but would include substantially improved avation facilities (maybe even a through deck design) for operating a variety of UCAV's as well as helicopters.
Its boat handling facilities would consist of an extendable rail system from the transom, similar to that in the Danish Absalon support ships, allowing it to operate a variety of manned and unmanned craft as dictated by the mission.
Such a ship would be highly automated with a reduced crew (less than 100) but substantial accomodation for additional personnel as required.
Above all with its increased size it would be highly suvivable, extremely versitile and easily and affordably upgradeable.
