About Taylor Model Basin Federal Credit Union


The TMB Federal Credit Union was chartered in March 1942. The credit union is a corporation chartered under the laws of the United States.

The credit union is a voluntary, not-for-profit cooperative association originally organized by a group of people employed with the David Taylor Model Basin in Carderock, Maryland (currently known as the Naval Surface Warfare Center, Carderock Division). It is democratically administered to encourage thrift among its members, create a source of credit at a low rate and provide maximum service at minimum cost.


The field of membership shall be limited to those having the following common bond:

  1. Civilian and military personnel of the U.S. Government who work at or are paid by/through the Naval Surface Warfare Center, Carderock Division, in the United States;
  2. Contractors and employees of contractors who work regularly at the Naval Surface Warfare Center, Carderock Division, under contract with the U.S. Government; and
  3. Spouse of persons who died while within the field of membership of this credit union; employees of this credit union; persons retired as pensioners or annuitants from the above employment; and members of their immediate families.

It is the policy of this credit union "Once a Member Always a Member" in order to protect those individuals who are at risk of losing their membership because they are no longer within the field of membership (for example a change of jobs, transfer out of the city, etc). This policy does not protect those individuals who voluntarily terminate their membership with the credit union.
