We know that two VOC ships armed with 70 guns fought in the Battle of Lowestoft in June 1665. It turns out that we know the armaments of those two ships, although we don't know which one has a specific armament. The two ships were the Delfland and the Huis te Zwieten. De Jonge, in an appendix to Vol.I of Geschiedenis van het Nederlandsche Zeewezen lists the armaments of the two ships. They are as follows:
VOC ship 1
70 guns:
1-36pdr
4-24pdr
21-18pdr
20-12pdr
24-8 and 6pdr
VOC ship 2
70 guns:
4-24pdr
22-18pdr
6-12pdr
20-8pdr
14-4pdr
4-smaller
We do know the armament of the Huis te Zwieten in 1654, which consisted of 60 guns, but this doesn't really help much with the armament in 1665:
10-24pdr
16-18pdr
24-12pdr
10-6pdr
