What would make a paper BCG proposal plausible?

How likely is the viewer's paper BCG proposal to be built by the RCN, RN, or USN?

The RN or USN is more plausible than the RCN, but the answer depends on the post-Type 45 programme and the U.S. large-surface-combatant path.

The viewer's proposed BCG characteristics are unspecified, so only its procurement context can be assessed. The Royal Navy or U.S. Navy is considered somewhat more likely to pursue it than the Royal Canadian Navy. The British path depends on what follows the Type 45 destroyer, while adoption of a comparable U.S. large surface combatant could make a British follow-on more plausible. A live programme and alliance pathway would be needed to turn the paper concept into a funded requirement.
