This item is an injection-plastic ship model kit. It requires both cement and painting to complete or use.
Okay, these ships were basically torpedo fodder for US subs, but my gosh, look at the crisp detail! Pit-Road doesn't let up, even when the subject matter is hardly glamorous. Originally these vessels started the war unarmed, but were slowly beefed up during the conflict. By war's end, they were too outdated to keep up with big ships and relegated to other duties. They were all eventually sunk by the US.
