Ladies and Gentlemen:

     Pursuant to Rule 461 under the Securities  Act of 1933,  GSE Systems,  Inc.
(the  "Company")  has  requested  that  the   effectiveness   of  the  Company's
Registration Statement on Form S-2 (File No. 333-126472) be accelerated to 11:00

        The Company acknowledges that:

     *    should the  Commission  or the staff,  acting  pursuant  to  delegated
          authority,  declare the filing  effective,  it does not  foreclose the
          Commission  from taking any action with  respect to the filing;

     *    the  action  of  the  Commission  or the  staff,  acting  pursuant  to
          delegated  authority,  in  declaring  the filing  effective,  does not
          relieve the Company from its full  responsibility for the adequacy and
          accuracy of the disclosure in the filing; and

     *    the  Company  may not assert the  declaration  of  effectiveness  as a
          defense in any  proceeding  initiated by the  Commission or any person
          under the federal securities laws of the United States.

                                        Sincerely,
                                        GSE SYSTEMS, INC.
