Slow, pathetic range, meagre weapons load compared to just about anything (F-15, F-14 and certainly F-111).
It was very much a 'toy' and the -18F has the similar pathetic range, slightly larger load but similarly slow as a wet week compared with say, the F-15SE. But I understand why we bought them as a gap-filler (they were never even close to an F-111 replacement, nothing came close, except maybe the 15SE) and we already had an installed base of the earlier model.
