sentences:  In a separate study in 1993, two French students had been assigned the design of a Large Capacity Missile Ship, a 20,000-tonner with 500 VLS cells filled with land-attack missiles.This design was inspired by a RAND paper in that year, which suggested a land invasion could be halted by destroying 20% of its vehicles with precision munitions.This would take several days with aircraft, but a surface ship with large numbers of land-attack missiles could achieve the same effect almost instantly.
