Pacific Northwest transit toward Keyport, Washington, United States Navy
The USS Tiru USO Claim
Milton William 'Bill' Cooper later claimed that while serving aboard submarine USS Tiru in 1966 he and other sailors saw a huge metallic disc repeatedly rise from and re-enter the sea. His first public account appeared on the ParaNet bulletin-board system in 1988, more than twenty years after the al
Why This Case Matters
An influential naval-USO story because Cooper became a major conspiracy figure, but the actual case provenance is late and almost entirely dependent on him.
Chronology
- 14 Jun 1966 Tiru departs Hawaii for Keyport
- alleged lookout sighting occurs during transit
- no contemporaneous public report located
- summer 1988 Cooper posts account on ParaNet
- story becomes part of Cooper/Lear UFO-conspiracy narrative
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Misidentified naval activity, ship/aircraft/balloon, oceanic visual illusion, memory distortion or fabrication remain strong possibilities. Cooper's later conspiracy career materially weakens but does not by itself disprove the original claim.
What Remains Unresolved
- Exact date/location
- deck log
- watch bill
- names/statements of alleged other witnesses
- any sonar/radar record
- why no contemporaneous report exists.
Key Takeaways
- Official ship history confirms Tiru was on the relevant Hawaii-to-Washington transit, not that the USO event happened. Keep those two facts separate.
