US Marines to get high-speed, radar-evading electric seagliders for rescue ops

is this a ground effect machine?

"seaglider" is apparently a new word for ekranoplan. The difference is, the new ones tend not to be so enormous [1].

See e.g. https://www.regentcraft.com/seagliders/viceroy and https://www.hawaiiseaglider.org/what-is-a-seaglider

It's the same craft with a different paint job

Yes, they are Wing-in-Ground craft

Thank you for bringing this up. All the marketing (and the "journalism" regurgitating it) are writing as though 'seaglider' is a word I ought to be familiar with, but have never encountered before. I had a lot of "these things seem a lot like an ekranoplane variant, but they're not calling them that" puzzlement.
