Yes, the PzH2000 is pretty impressive. The Crusader would be even more
so, if the US Congress ever gets its collective thumb out and approves
funding for the final development and production.

The main problem with the Time-On-Target fire pattern is that the
maximum range gets severely restricted for large numbers of
projectiles. Not a big problem with a 3-round burst (12 seconds), but
IIRC you lose about 10 km maximum range with a 10-round TOT salvo
compared to a the maximum range of a single round - that's 20-25% off
the range of the PzH2000.

And, of course... there's the CB aspect too. The inital rounds of a
large TOT salvo need to go in a very high trajectory, which makes them
comparatively easy for CBRs to spot - so firing from a single location
for one full minute might not always be a very good idea :-/

OTOH, it should be more difficult for the upcoming ADS defences to
counter a TOT salvo than it would be to stop individual shells.
