October 22, 2001


Raytheon Company
141 Spring Street
Lexington, MA  02421


Ladies and Gentlemen:

         I am Senior Vice President and General Counsel of Raytheon  Company,  a
Delaware  Corporation  (the  "Company"),   and  am  rendering  this  opinion  in
connection  with  a  registration  statement  on  Form  S-3  (the  "Registration
Statement")  to be filed today by the Company with the  Securities  and Exchange
Commission (the "Commission")  under the Securities Act of 1933, as amended (the
"Securities  Act"). The Registration  Statement relates to the proposed issuance
and sale pursuant to Rule 462(b) under the Securities Act of up to  $175,937,500
aggregate initial offering price of the Company's common stock,  $0.01 par value
per share (the "Common Stock").

         As Senior Vice  President  and General  Counsel of the Company,  I have
examined and am familiar with the Restated  Certificate of  Incorporation of the
Company,  as amended to date. I am also familiar with the corporate  proceedings
taken by the Board of Directors  of the Company to  authorize  the filing of the
Registration Statement and the issuance of the Common Stock.

         In connection with this opinion, I have examined  originals,  or copies
certified  or  otherwise  identified  to my  satisfaction,  of  such  documents,
corporate   records  and  other  instruments  as  I  have  deemed  necessary  or
appropriate for the purpose of this opinion.

         In connection with the foregoing,  I have assumed:  (i) the genuineness
of all signatures on all documents  examined by me, (ii) the authenticity of all
documents  submitted to me as originals  and the  conformity to the originals of
all documents submitted to me as copies, (iii) the Registration  Statement,  and
any amendments thereto (including post-effective  amendments),  will have become
effective under the Securities Act; (iv) a prospectus  supplement will have been
filed with the  Securities and Exchange  Commission  describing the Common Stock
offered  thereby;  (v) all  shares of Common  Stock  will be issued  and sold in
compliance with applicable  federal and state  securities laws and in the manner
stated in the Registration  Statement and the applicable prospectus  supplement;
(vi) a definitive  purchase,  underwriting or similar  agreement with respect to
any shares of Common Stock  offered will have been duly  authorized  and validly
executed and delivered by the Company and the other parties  thereto;  and (vii)
there will be sufficient  shares of Common Stock  authorized under the Company's
Restated Certificate of Incorporation and not otherwise reserved for issuance.

         Based upon the foregoing,  and subject to the assumptions,  limitations
and qualifications set forth herein, I am of the opinion that:

1. The Company is a corporation duly organized and validly existing in good standing under the laws of the State of Delaware. 2. The shares of Common Stock registered under the Registration Statement, when duly authorized and issued for consideration having a value not less than the par value thereof, will be validly issued, fully paid and nonassessable. I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to me under the heading "Legal Matters" in the prospectus supplements and prospectuses constituting a part of the Registration Statement. In giving such consent, I do not thereby concede that I am within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder. Very truly yours, /s/ Neal E. Minahan Neal E. Minahan -2-

                                                                    EXHIBIT 23.2
