    Warship refueling at sea - GIFs

    Warship refueling at sea. This is known as UNREP (underway replenishment) or RAS (replenishment at sea).

    First a line-throwing gun is used to shoot a line between the two ships:

    Then the line is used to connect a larger fuel hose:

    I remember it well. Standing with a sledge hammer waiting to give the pelican hook a good smack to break free if the proverbial hit the fan.Name:  pelican hook.jpg

    Smoke makes electronics work, if it escapes the equipment breaks.
    Got to keep the smoke in.

    Was 1 of the line for fuel and the other for vapor transference to reduce any possibility of salt saturated air spray from entering either the tankers or the tanks of the ship receiving fuel.That seems like how I might have set it up.
    Never try to tell me it can't be done
    When I have to paint I use

    Yes, that's how we do it. UNREP: Underway Replenishment.
    My [not my as in personal, lol] aircraft carriers often fueled/ supplied 2 ships at a time port and starboard. MeJasonT might confirm each completed UNREP,'s emergency breakaway would be practiced. Certain hazards were avoided instead of saying "Emergency....", a musical signal was used. For the USN, one popular signal is "Bad to the Bone", George Thorogood, rather appropriate, but "Pipeline", The Ventures is clever too.
    This time last year [2017] marked 100th anniversary of replenishment underway. There are so many incredibly interesting details about UNREP. I still marvel today, 1700 miles from salt water; who knows how far from ocean open to steam 3-4 hours unimpeded.
