A proforma for extracting dimensions and similar data from June’s has been
completed as Table 1.4 with data on modern frigates and corvettes. Column 9 in
this table is included in an attempt to make sense of the big differences in BID and
TID which result from the extremes of short and very lengthy superstructures.
