Another problem is look at a US carrier group.
CSG or CVBG normally consist of 1 Aircraft Carrier, 1 Guided Missile Cruisers (for Air Defense), 2 LAMPS (Light Airborne Multi-Purpose System) Capable Warships (focusing on Anti-Submarine and Surface Warfare), and 1–2 Anti Submarine Destroyers or Frigates
Have we got enough spare navy ships to do that now, plus fulfill other commitments???
