In the mid to later 60's while "vacationing" in SE Asia, most of our
in-country net frequencies were in the 5 MHz range. Generally, it was
100W [KWM2A] to a low dipole [GRA-4]. From Vietnam, we had no problem
with stations in the Philippines, Thailand or anywhere in-country.
That's about 8 dB more than your 15W, a tad over 1 S-unit.
Having CW and Data [<2.8 KHz BW] as well as USB is probably more
important than power. 5 MHz sometimes went long after sunset but still
worked.

Dear Elecrafters, Local telecommunication authority is considering
60m operation for the hams in VR2. For output power of 15W PEP, using
a dipole for NVIS, what would be the likely usual communication range
7/24 round the clock? 100km radius? Any advice will be appreciated
and thanks for the band width here. 73 Johnny VR2XMC
