Well, with that low-set (A4) wing , nuke or not, the space for a hefty bombload (plus tanks) and some bringback capability sorta would call for some long gear struts.
The relatively high, narrow, skinny gear were a significant problem for NUGGETs and STUDs and in reality -- any unwary or complacent Aviator -- when faced w/ a wet-runway, strong X-wind landing situation ... and many of those events resulted in off the runway excursions.
I can't remember the X-wind cut-off, but taking the field gear on a wet/strong X-wind landing was SOP. It could make life hell on those following you, so some headwork and planning was required to get all aboard ... especially when there was no other runway option available.
