While not up to WEM standards, they are nevertheless excellent for a resin kit. Ideally there would be two of each, as the ship carried both in her career. This is to be expected with such a long fine hull though. There is etched brass for this radar on the set, so you will have to remove the cast on radar. I honestly don't know how the kit could be improved.
Etched brass is included for necessary parts, but most detail is cast in the mold.
ISW is a good example of this. Relies on etched brass for detail, while the casting has less overall detail. WEM is a good example of this. The CW Alaska on the other hand is the best of both worlds. The casting has as much detail as an ISW kit, plus the extensive etched brass of a WEM kit.
