Missile Assembly and Warhead Building

Overview

Part of the HM-69 Nike Missile Site, the Missile Assembly and Warhead Building is where crews tested and assembled Nike-Hercules missiles during the Cold War. It’s a rare look at military infrastructure tucked deep in the Everglades, and it’s far more compelling than the bunker-like exterior suggests.

What You'll See

• The assembly hall itself, with massive hangar doors and intact fixtures from the 1960s.
• A Nike-Hercules missile displayed as if being unpacked from its tube, plus original testing/control panels that show how crews worked the line.
• The broader HM‑69 complex around it: three missile barns/shelters, a guard dog kennel, and support buildings that round out the story.

Why It’s Special

It’s one of the few accessible former Nike missile bases in the country—and the only one preserved inside a national park. The building and site are listed on the National Register of Historic Places, and the interpretation here makes the Cold War feel immediate and local.

How to Visit

Access is commonly ranger‑guided; when open for drop‑in hours, you can also explore self‑guided via on‑site signage. Expect minimal amenities and an exposed setting—bring water and sun protection. Parking is available at the site.

Wildlife

You’re in the Everglades, so you may spot wading birds or an alligator along the drive. Inside the developed missile complex itself, wildlife sightings are fewer due to the open, paved grounds.

Best Time to Visit

• Season: Winter is the sweet spot, when programs and open hours are most reliable.
• Day/time: Arrive near the start of posted hours to catch a ranger program and beat heat; the site is exposed and can feel harsh by midday.
• Photography: The big-door reveal and interior displays photograph best when the doors are open; glare is common under bright sun, so overcast light helps.

Quick History

Opened in 1964 and staffed by roughly 140 soldiers, HM‑69 defended South Florida through the tense decades after the Cuban Missile Crisis. The base closed in 1979 and today is preserved by the National Park Service as a teaching site.

Is It Worth It?

If you’re even mildly curious about Cold War history, yes—this is a concentrated, well-told story in an evocative place. For pure wildlife viewing, other parts of the park are better; come here for context and the wow-moment when those big doors roll open.
