We (the US) managed to pack one into an 6" artillery shell that weighed 118 lbs (or 128lbs for the second version) - the W48 [1]. That's much smaller than a suitcase. Heavy, sure, but quite a bit smaller than the carry-on suitcase I was lugging around last week, and I've got a small one compared to the monstrosities that are considered to be carry-on sized now.
