Description
A stock rocket called GDLV3 Tanker. Built with 66 of the finest parts, its root part is fuelTank.long.
As the name indicates, this craft, like the GDLV3 Station, is a modification of the stock GDLV3 craft, as befits the GDLV3’s promised versatility. As the name also indicates, this craft is a fuel/oxidiser tanker (much like the GDLV3 itself, in fact), which, in the attached picture album, can be seen augmenting the propellant supply of (not-so-coincidentally) the GDLV3 Station.
The core stage, complete with deorbit and recovery system, is the same as that used on the GDLV3 Station.
Built in the VAB in KSP version 1.9.0.
