GDM complex

Nuclear-tipped ground defense missiles (GDMs) are cheap but deadly defenses for underdeveloped worlds. Each GDM site  contains a single missile, which is expended on use.

build time: 4 watches

minimum tech level: atomic (3)

Upgrade to: hypersonic missile complex?

Strategy notes:
GDMs vulnerable to mass swarms of Vangaurd-class explorer ships. Here is a table listing fights between Vanguard Explorers and GDMs. No other ships were present.

Stinger-class jumpships will shoot down GDMs. ~300 Stingers defeated ~1300 GDMs with negligible losses.

Adamant-class jumpships appear to outrange GDMs competely.
