Source-derived summary

Constant Warwick was originally a 32-gun privateer, built in 1645 as a private venture between the Earl of Warwick and Sir William Batten and intended to operate as a privateer. Hired for service in the Parliamentarian navy during the First English Civil War, her captain William Batten defected to the Royalists during the 1648 Second English Civil War. After her crew mutinied in November 1648, she returned to England and was purchased by Parliament for the Commonwealth Navy on 20 January 1649.

Described as an "incomparable sailer", she was noted for her sharpness and fine lines, and was considered by some as the first true frigate of the Royal Navy (although the Expedition and Providence of 1637, which predated her by eight years and originally described as "pinnaces", were certainly categorised as frigates by the time of the English Civil War). Mainly used for patrolling, she was captured by the French in 1691.

Constant Warwick was the only ship of the Royal Navy to bear that name.

Construction and specifications

She was started as a private venture contracted to Peter Pett I of Ratcliffe and launched in 1645. Her dimensions were keel 85 feet 0 inches (25.9 metres) keel for tonnage with a breadth of 26 feet 5 inches (8.1 metres) and a depth of hold of 13 feet 2 inches (4.0 metres). Her tonnage was 315+48⁄94 tons. She was remeasured at a later date and her dimensions changed to keel 88 feet 0 inches (26.8 metres) keel for tonnage with a breadth of 27 feet 0 inches (8.2 metres) and a depth of hold of 12 feet 0 inches (3.7 metres).

Editorial analysis

Why this record matters

The phrase “1645 fourth-rate” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 2, 2026. The linked authority identifier is Q5631950. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1645, 1648, 1649 and 1637.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
