Strategic sealift and land-based prepositioning

What would replacing US Army afloat equipment with land-based prepositioning mean for onward deployment?

Land-based equipment may still need loading aboard ships for onward deployment; the proposal's adoption is not confirmed in this exchange.

Clarke discusses land-based prepositioning as a reported proposal, with its adoption left unconfirmed. In his comparison, land basing can look cheaper on paper. Equipment stored ashore may still have to be loaded onto a ship to reach its deployment area. Afloat equipment already has the means to move across a theatre.
