Human Factors; Procedure
On approach to ILS; vectored in high and tight. After localizer capture; aggressive descent was required to capture the glideslope. This aggressive VVI towards the ground caused the Terrain Awareness Warning System (TAWS) to activate. In IMC; at the same time the terrain warning went off; we lost all ILS signal capability on both sides; to include flight directors. As a gut reaction to a terrain warning (TAWS; not GPWS) I performed an aggressive go-around and blew through the missed approach altitude (1;500 FT; then 3;000 FT MSL) by about 1;100 FT; eventually leveling off at 4;150 FT MSL; flustered with a hand-full of airplane. Tower was notified and they passed the word to Approach; who thankfully said 4;000 FT was fine.The sequence of events was debriefed on the ground by the crew and with [Approach.] I should have continued the approach to the MAP and executed the missed in accordance with the published procedure.
C-17 First Officer reported they received a terrain warning while on final approach; they executed a go-around and overshot the missed approach altitude by about 1;100 FT.
