Exhibit 99.1

      GenCorp Announces the Receipt of a Commitment Letter for a Syndicated
                      $175 Million Secured Credit Facility

    SACRAMENTO, Calif., Nov. 8 /PRNewswire-FirstCall/ -- GenCorp Inc.
("GenCorp") (NYSE: GY) announced today that it has received a commitment
letter from Wachovia Bank, National Association for a syndicated $175 million
secured credit facility that will replace its current credit facility.  The
revolving credit facility portion of the facility is anticipated to be
$75 million and to mature five years from the closing date of the facility.
The $100 million credit-linked portion of the secured credit facility is
anticipated to consist of a six-year $25 million term loan subfacility and a
six-year $75 million letter of credit subfacility. The maturity dates may be
accelerated to January 2007 if the Company's 5 3/4% convertible subordinated
notes remain outstanding at that time.
    The facility will be secured by a first priority pledge of the capital
stock of certain of the Company's subsidiaries and substantially all of its
tangible and intangible assets.  In addition, the Company's material domestic
subsidiaries will unconditionally guarantee its obligations under the
facility.
    The consummation of the new credit facility is subject to a number of
terms and conditions, including the closing of the Company's announced common
stock offering, negotiation of definitive loan documents and satisfactory
completion of due diligence.  Because the definitive loan documentation is
subject to negotiation and subsequent syndication, the final terms, conditions
and covenants of the new credit facility may differ from those described
herein.
