I'm embarrassed to say I didn't even know we were in the market for these things but, there you go -- The Canadian Army just became the first international customer for Raytheon's 'Bunker Buster' missiles. Canada will be spending $17-million US ($16.75 million CDN at today's rates) to buy 462 TOW (Tube-Launched, Optically-Tracked, Wire-Guided) Bunker Buster missiles. The TOW weapon system -- you probably knew -- is "the world's premier long-range precision anti-armor, anti-fortification, anti-amphibious landing weapon."

Assuming a kill rate of 100 per cent, it will cost about one Lexus IS 250 or $37,000 US every time a TOW blows something up on behalf of Canada.
