(TAOEs). In these designations, T means the ship is
operated by the Military Sealift Command (MSC) with a
mostly civilian crew, A means auxiliary ship, O means
oiler, K means cargo, and E means ammunition (i.e.,
explosives). These CLF ships are large auxiliary ships.
Anti-access/area-denial (A2/AD) capabilities aim to create a
defended area around a country that in time of conflict
would be a “no-go zone” for opposing military forces.
Operational concepts are general approaches for how to use
military forces for achieving certain objectives. Fleet
architecture refers to the types and mix of ships that make

up a navy.
