To be fair, Spanish and Netherlands (Dutch) navy are quite active in 1400s and no way if they are going to count China as "top 5 strongest" and does not consider the Spanish Navy and Dutch navy.
Zheng He Fleet manage to transverse Indian Ocean and into North Africa, but the Spanish and Dutch at that era covered half the Globe...

Is there any contest?
To much of a lesser extend, the French navy are at least equal if not stronger than Royal Navy.
Europe is nonetheless a seagoing nation.
If I have to choose top 5 Naval power at all time I would choose
Ancient Egyptian Navy (Ancient <1500BC) -> Greek Navy (Middle Ages (500 to 1500 AD) -> Spanish Navy (Age of Discovery 1400-1800AD) -> Royal Navy (Early Modern Time 1800-1900 AD) -> USN (Modern Time1940-now)

Firstly, when I don't have much time online I usually pass your mentions to reply them more focused and more involved with a more free time. But again, I found out that you have tagged me in a thread where I opened when it picked my attention.. Lol.
Anyways, I believe it's not possible to make such rankings in which my English isn't good enough to explain. I will try with an example. If, you look at UK today, it is clear that it gets its strength from his historical colonies in which was achieved by its glorious Navy. So based on that, if UK is the UK we know today, it certainly owes that to Her Majesty's Navy, but these happened in colonial era where the Naval warfare wasnt evolved much and the humankind was in the realization of the importance of naval power because of the geographical explorations. That's what I'd call the Nu1 of all the time.
On the other hand, we have the USN. Some journalists refer to it as "America's Foreign Policy Sheriff" or things like that. It's involvement in every conflict it took part. WW2 success. Deployed nearly in every corner in the Blue World. And of course the US Marine Corps which is technically a division of the USN. Like that of RN's role in past USN has been an absolutely incredible asset for US' foreign policy enforcement. But these happen in the modern world, where the former superpowers like Russia (USSR) didn't put importance on the Navy as US did.
Spain and France did also good. Instead of ranks, I am grouping them in two separate classifications:
All the time (Alphabetical order):
Tier 1: RN, USN
Tier 2: Japan, France, Spain
TierX: the Netherlands, Portugal, Italy (Including state-cities like Venice...etc.)
Unfortunately, Ottoman Navy had his golden age even once ruled the Mediterranean but Sultans didn't give enough importance so not on the list.
For Post-WW2/Post-ColdWar:
A: USN
---gap---
B/C/D: the rest of the World.
I can't give predictions because foremost everything ranking military forces itself is a dumb thing for us and you can't actually know all the fact unless there's a war, God forbid.
(I wont give names not to disrespect those navies and to get keyboard sailors here) And because that in today's world there are;
- Advanced and large navies that face severe maintenance problems and too many accidents.
- Small and relatively incapable near it's neighbors but has second-strike capability.
- Large, powerful, nuclearly armed but junk equipment.
- Large, expanding and getting more advanced day by day but filled with corruption to the teeth.
- Have powerful deterrent submarine force and modernizing itself to be a blue water navy, 924 years of tradition but thanks to its government, all professional experienced staff is either purged with made up cases or forced to resign.
Some of these above either don't have his own defense industry or in the process of making it.
But besides all these there are countries performing pretty well that deserve a credit:
UK, France, Spain, Italy, Japan, South Korea.
And we have Russia that's did well in past and wants to be back on the stage again.
P.S I didn't take Ancient Civilizations into account.
