The 1677 Construction Programme was a group of Royal Navy ships of the line approved on 5 March 1677.
This program authorised the construction of thirty new warships for the Royal Navy and was a compromise between the 40 ship programme proposed by Samuel Pepys in 1675 and the Parliamentary counter proposal of twenty ships in 1676.
Three vessels (Lenox, Hampton Court, and Captain) were initially to be completed with only twelve-gunports on the upper deck per side.
The actual composition of the gun armaments varied and will be specified on the individual ship articles.
Four vessels would be named for the illegitimate sons of the King, Charles II.
