Yes, except for one small problem.

Wave propigation (sp for both of us!). Even if you focus the energy more than
present methods do, _off_ the transmitter, you will run into the limit of
boiling water. US active Sonar can and does do this, under some
situations...the SONAR is powerful enough to boil the water off from around the
transducer, which produces a lot of steam, but not much in the way of
detection. The SONAR which is certanly capable of doing this is the one on LA
class subs, because when you are deep you can put much more power into the
water than at shallow depths without this happening (because of
pressure/boiling temp relationship). IIRC, the active array on a LA can get to
about 220 dB on the face of a transducer.

the caseless (G7?) I _think_ is the only one that could do that, because no
case to eject after firing. It's still under development AFAK, and may never
see service.
