Type 22 provides a larger example of hull growth between batches. The lengths quoted rise from 131 metres for batch one to 148 metres for batch three. That 17-metre increase exceeds ten percent of the original length, compared with less than two percent for the Perry's two-metre extension. The comparison questions how much descriptions such as long hull or broad beam reveal without the actual dimensions.

Perry and Type 22 hull growth compared
A 17-metre increase across Type 22 batches puts the Perry's two-metre extension into perspective.
