>>Well, a fast attack sub or aircraft carrier could theoretically beat the time on the JV course, it would not be "easy." The top speeds of these vessels are classified, but standard operation procedures would not allow these speeds for this length of time. The carrier would need to ditch the other ships in the carrier group (none of which could maintain 26 kt for any length of time), which would leave the carrier without defensive weapons and would require exceptional circumstances. The sub could not maintain this speed on the surface but could when submerged, however standard submerged cruise speeds are less than 26 knots, so you would need a very good reason to exceed standard speeds.

Interestingly, BP5 has substantially exceeded the top speeds of both nuclear subs or aircraft carriers. While we do not know the precise limits they are certainly in the low 30 knot range. I believe that no nuclear powered ship has ever done 45 knots nor an 800 mile day, which BP5 has done several times.

As a practical matter, I strongly suspect that 45 days for a 26,000nm non-stop route is a absolute record for a surface ship regardless of propulsion, wind, steam, oil, or nuclear. The other boats that might be able to beat that time, are extremely unlikely to attempt that course for practical reasons. <<
