HG effectively made B2 obsolete.
The problem with this claim is that GDW revised and reprinted CT with the LBB2 starship design system well after the release of the second edition of High Guard. (HG 2nd came out in 1980; CT LBB 2nd came out in 1981; The Traveller Book came out in 1982 and Starter Traveller in 1983).
In addition, High Guard explicitely allows ships to use Book 2 drives (HG 2nd p23).
So GDW never took the position that High Guard replaced the LBB2 system or rendered it obsolete.
I'd also note that the HG combat system has serious flaws when dealing with smaller warships without spinal mounts (under ~20kton in my experience at TL 14-; under ~10kton with TL15 power plants). Only spinal mounts have ratings of A+. And weapons of ratings of 9- have a +6 on the damage table. Armor adds to the damage roll and is only limited to tech level. This can easily result in warships that can't really hurt each other. For instance, I rerated my Book 2-designed "Virginia" class 5kton battleship in High Guard. The TL 12 ship had an armor factor of 12 and carried a maximum weaponry load (3 100 ton missile bays; 20 turrets/or 2 more 100 ton bays). The armor modifier (+12) and weapon factor 9- modifier (+6) meant that each hit would damage the ship only on a 2d6 roll of 3-. The only effective solution would be to use nuclear missiles, which would cause damage on a roll of 9-.
A battle between sensibly designed non-spinal mount warships* would be miserably unplayable unless both sides used nuclear weapons. Not my kind of universe.
EDIT -- the rule that allows weapons to score critical hits equal to the difference between the weapon code and target's size code offers minimal relief (and none at all if we're talking about sensibly armored ships bigger than ~200 tons).
*At TL13+, meson gun bays offer some theoretical ability to cause damage, since armor does not affect them. But they are effectively unable to penetrate even level 1 meson screens (a TL15 100 ton meson gun bay needs a 12+ to penetrate a level 1 screen), so this ability is largely theoretical. Meson screens are small and relatively cheap -- 90 tons at TL12; 30 tons at TL 13; 16 tons at TL 14. They are a very minor expense on 1000 ton+ ships.
And TL12- designs can't have meson gun bays.
