Fort Salisbury USO Sighting

The Fort Salisbury USO Sighting occurred in 1902 in the Gulf of Guinea, Africa, when four men aboard the ship Fort Salisbury witnessed an immense cigar-shaped object sink into the ocean. The object was estimated at nearly 200 meters long and 300 meters wide — dimensions that would make it larger than any submarine ever built — and was observed with distinct colored lights at both ends as it submerged.

Incident Description

Four witnesses aboard the Fort Salisbury observed the object descending into the ocean. Key characteristics:

  • Shape: Cigar-shaped
  • Dimensions: Approximately 200 meters long and 300 meters wide
  • Lights: Two orange lights at the front end; two blue-green lights at the other end
  • Behavior: The object passed under the vessel as it sank below the surface
  • Location: Gulf of Guinea, off the coast of Africa

Assessment

UAP Gerb acknowledges that the size, location, and era could potentially point to a submarine explanation, noting that the case occurred in a period when submarine technology was developing rapidly. However, the dimensions reported are assessed as anomalous: the early German U-boats that represented contemporary submarine technology measured approximately 41 meters in length, making the reported Fort Salisbury object nearly five times longer than the most advanced submarines of the period. The distinctive colored lights — orange at one end, blue-green at the other — are not consistent with any known submarine navigation or running light configuration of that era.
