I&#x27;d say it was too expensive to be used, otherwise they&#x27;d be used more often. Also one of them did not explode as intended due to the primitive detonation mechanism, so there was some technical difficulties involved (at a time when they barely started using matchlocks, not even the more advanced and successful flintlocks).<p>It was basically the equivalent of a boat filled with TNT as I understand, not <i>that</i> powerful.<p>Could&#x27;ve been very useful at wiping out ports, cities and fleets, at the time, I doubt they had <i>any</i> qualms about it :-).<p>Also, not that much of a war deterrent, as history can attest, lol...
