The Canadian navy is drafting a plan to acquire two large amphibious assault ships capable of transporting thousands of troops and dozens of tanks and trucks across the seas, according to a report in The Brandon Sun. The idea, which merited a passing reference in last spring's defense policy statement, is expected to go before the federal Treasury Board next year for consideration, said the director of the navy's maritime requirements. The acquisition of the ships, that can resemble small aircraft carriers, are in addition to the navy's $2.1-billion project to build three regular supply ships. In April, Ottawa laid out a sweeping new plan for its Armed Forces, promising a better-equipped, more efficient and more effective military at home and abroad - all within five years.
