Dear Mr. Flinn:

          Re:              Advanced Communications Technologies, Inc.
                           Form 10-KSB for the Fiscal Year Ended June 30, 2005
                           Form 10-QSB for the Quarter Ended September 30, 2005
                           File No. 0-30486

The  following  are  your  comments  reproduced,  along  with our  responses  in
connection  with your March 15,  2006  comment  letter,  which  reviews our Form
10-KSB for the fiscal  year ended June 30,  2005 and Form 10-QSB for the quarter
ended September 30, 2005.

Note 9 - Notes and Loan Payable, page F-1A

COMMENT 1 We note your response to our previous comment four. Please address the
          following comments:

          o         Tell us if the deferred  finance fees were costs incurred to
                    enter  into  the  loan  transaction   (e.g.,   lawyer  fees,
                    accountant  fees,  etc.) or a fee charged by Cornell Capital
                    Partners LP to borrow the money over the life of the loan.

          o         Explain  to us the basis for your  assertion  to the  effect
                    that the promissory  note was issued in connection  with the
                    equity line of credit;  tell us the  expiration  date of the
                    equity line of credit.

          o         We note that the loan was originally  payable in six months,
                    would  become  interest-bearing  at the  lower of 24% or the
                    highest rate  permitted by law if not paid when due, and was
                    subsequently   modified.   Please  explain  to  us  how  you
                    considered  EITF 96-19 in  determining  how to  account  for
                    these modifications.




RESPONSE            The following responses correspond to Comment 1:


          o         The  deferred  financing  fees  in the  amount  of  $171,000
                    represent   financing   fees  charged  by  Cornell   Capital
                    Partners, L.P. to borrow funds over the life of the loan. It
                    does  not   represent   loan   transaction   costs  such  as
                    professional fees for lawyers and accountants.

          o         The Equity Line of Credit  agreement  was  effective in July
                    2003 and still remains in effect.  It is scheduled to expire
                    in February 2007 unless  extended by mutual  agreement.  The
                    promissory  note was  issued in  connection  with the Equity
                    Line of Credit  transaction  because by its terms,  the note
                    was to be  repaid  either  in cash or from the  issuance  of
                    common  stock.   The  maturity  of  the  note  preceded  the
                    expiration of the Equity Line of Credit.

          o         When we modified the unsecured  promissory  note in February
                    2005,  we  considered  the  application  of EITF  96-19  and
                    determined  that the  change in terms was not a  substantial
                    modification  of the debt  instrument  because  the  present
                    value  of  the  cash  flows  under  the  terms  of  the  new
                    instrument  is not at least 10%  different  from the present
                    value of the  remaining  cash  flows  under the terms of the
                    original  instrument.  This present value  computation  took
                    into account those attributes  stipulated by the EITF in its
                    discussion.


In connection  with its response to the comments of the SEC staff  regarding the
above referenced 10-KSB and 10-QSB, Advanced Communications  Technologies,  Inc.
(the "Company") acknowledges that:

      o     the Company is  responsible  for the  adequacy  and  accuracy of the
            disclosure in the filings;

      o     staff  comments  or  changes  to  disclosure  in  response  to staff
            comments do not foreclose the Commission from taking any action with
            respect to the filings; and

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

                                    * * * * *
