Lockheed Martin Buys Canadian Undersea Defense Firm, Sparking Concern at Home

From our other sites

The story

U.S. defense and aerospace giant Lockheed Martin has reportedly acquired Ultra Maritime, an undersea defense company based in Dartmouth, Nova Scotia, for $3.45 billion USD. On the Canadian Lemmy community c/canada, the news sparked criticism of Canada’s distinctive “branch-plant economy” mentality — the tendency to grow domestic companies only to sell them off to foreign capital. At the same time, some pointed out that Ultra Maritime was already foreign-owned to begin with, making this just a deal between two American companies, leaving commenters divided on how far the label “loss of domestic industry” should really be stretched.

Shouldn’t domestic industries be protected?

This is Canada's 'branch-plant economy' mindset right there — sell off your successful companies to foreigners and just watch everything go downhill.

Re: #2 If we keep selling off military-related stuff to the US like this, it might end up pointed back at us someday.

They talk tough and stoke patriotism over the Stelco situation, but behind the scenes they just keep selling everything off to foreign companies and billionaires.

Re: #4 Ultra Maritime has been foreign-owned for ages, so nothing really changes on that front. This is more of an industry-consolidation story — Lockheed already has an office in Dartmouth, so buying a company in the same town just means one less employer in town.

If a company has an office in Canada, this government treats it as a 'Canadian company.' This case is really just an American company selling to another American company.

Kind of sad… and yet we keep trying to put distance between ourselves and the US. Guess it all comes down to money in the end.

Re: #5 Here's another thing I learned today. I already knew that after Cobham shut down its Nova Scotia-based Cobham Tracking and Locating in 2013, some of the laid-off workers moved over to Ultra Electronics — but I had no idea that Cobham itself went on to acquire that very same Ultra Electronics in 2021. I wonder how any of Cobham's old employees who stuck around all this time feel about that.

Background and Key Points of This Discussion

Ultra Maritime wasn’t originally a Canadian-born company to begin with — it was a business unit left over in Nova Scotia under Britain’s Cobham (which later absorbed Ultra Electronics), so this acquisition is less a case of “a Canadian company being seized by foreign capital” and more a transfer from British capital to American capital. In the thread, the central debate was criticism of the “branch-plant economy”: the government talks tough and protectionist about domestic steelmaker Stelco, yet doesn’t intervene in deals like this one. The other recurring thread was security-related unease about Canadian-made military technology ending up in American hands, with some commenters worrying — amid shaky U.S.-Canada relations — that it could someday be turned back on Canada itself. Worth noting this remains speculative; no actual technology diversion has occurred.
