Declassified FBI Records Shed Light on 1984 Washington Navy Yard Bombing Investigation

Newly declassified FBI files provide a detailed look into the federal investigation surrounding the April 20, 1984, bombing of the Officers’ Club at the Washington Navy Yard. According to the documents, an improvised explosive device detonated in the reception area of Building 101 at approximately 1:55 a.m. While the blast caused significant concern, the facility was unoccupied at the time, resulting in no injuries. The FBI’s Washington Field Office launched an extensive inquiry into the incident, treating it as a potential act of domestic terrorism.

The investigation uncovered a complex web of conflicting claims regarding who was responsible for the attack. Shortly after the explosion, media outlets including the Washington Post and United Press International received phone calls and recorded messages from groups asserting they had carried out the bombing. One message attributed the act to the FALN in support of Puerto Rican independence, while another linked the explosion to the "Guerrilla Resistance Movement" as a protest against United States foreign policy in the Caribbean and Central America.

Authorities also tracked a series of mailed communiqués purportedly sent by the "Red Guerrilla Resistance." These letters frequently utilized a specific return address in Washington, D.C., but investigators eventually determined that the listed apartment number did not exist. These records, which include FD-302 interview reports and internal summaries, highlight the challenges federal agents faced while navigating anonymous threats and contradictory claims during the height of the investigation.
