Item 1.		Security and Issuer
		This Amendment No. 5 to Schedule 13D on the Class A Common Stock of
Kaman Corporation (the "Issuer") is being filed on behalf of the undersigned to
amend the Schedule 13D, as amended (the "Schedule 13D") which was originally
filed on November 9, 2001.  Unless otherwise indicated, all capitalized terms
used herein but not defined herein shall have the same meanings as set forth in
the Schedule 13D.

Item 2.		Identity and Background
This statement is being filed by Mario J. Gabelli ("Mario
Gabelli") and various
entities which he directly or indirectly controls or for which he acts as
chief investment officer.  These entities, except for Lynch Corporation
("Lynch") and Lynch Interactive Corporation ("Interactive"), engage in various
aspects of the securities business, primarily as investment adviser to various
institutional and individual clients, including registered investment
companies and pension plans, and as general partner of various private
investment partnerships.  Certain of these entities may also make investments
for their own accounts.
		The foregoing persons in the aggregate often own beneficially more
than 5% of a class of a particular issuer.  Although several of the foregoing
persons are treated as institutional investors for purposes of reporting their
beneficial ownership on the short-form Schedule 13G, the holdings of those who
do not qualify as institutional investors may exceed the 1% threshold presented
for filing on Schedule 13G or implementation of their investment philosophy may
from time to time require action which could be viewed as not completely
passive.  In order to avoid any question as to whether their beneficial
ownership is being reported on the proper form and in order to provide greater
investment flexibility and administrative uniformity, these persons have
decided to file their beneficial ownership reports on the more detailed
Schedule 13D form rather than on the short-form Schedule 13G and thereby to
provide more expansive disclosure than may be necessary.
		(a), (b) and (c) - This statement is being filed by one or more of
the following persons: GGCP, Inc.  formerly known as Gabelli Group Capital
Partners, Inc. ("GGCP"), Gabelli Asset Management Inc. ("GBL"), Gabelli Funds,
LLC ("Gabelli Funds"), GAMCO Investors, Inc. ("GAMCO"), Gabelli Advisers, Inc.
("Gabelli Advisers"), Gabelli Securities, Inc. ("GSI"), Gabelli & Company, Inc.
("Gabelli & Company"), Gabelli & Company, Inc. Profit Sharing Plan (the
"Plan"), MJG Associates, Inc. ("MJG Associates"), Gabelli Foundation, Inc.
("Foundation"), Mario Gabelli, Lynch, and Interactive.  Those of the foregoing
persons signing this Schedule 13D are hereafter referred to as the "Reporting
Persons".
		GGCP makes investments for its own account and is the parent
company of GBL.  GBL, a public company listed on the New York Stock Exchange,

registered under the Investment Advisers Act of 1940, as amended ("Advisers

		GSI, a majority-owned subsidiary of GBL, acts as a general partner

account.  It is the immediate parent of Gabelli & Company. GSI is the
Investment Manager of Gabelli Associates Fund, Gabelli Associates Fund II,

		For information required by instruction C to Schedule 13D with
respect to the executive officers and directors of the foregoing entities and
other related persons (collectively, "Covered Persons"), reference is made to
Schedule I annexed hereto and incorporated herein by reference.
(f) - Reference is made to Schedule I hereto.

Item 3.		Source and Amount of Funds or Other Consideration
		Item 3 to Schedule 13D is amended, in pertinent part, as follows:
		The Reporting Persons used an aggregate of approximately $2,976,446
to purchase the additional Securities reported as beneficially owned in Item 5
below since the most recent filing on Schedule 13D. GAMCO and Gabelli Advisers
used approximately $2,943,491 and $32,955, respectively, of funds that were
provided through the accounts of certain of their investment advisory clients
(and, in the case of some of such accounts at GAMCO, may be through borrowings
from client margin accounts) in order to purchase the additional Securities for
such clients.

Item 5.		Interest In Securities Of The Issuer
		Item 5 to Schedule 13D is amended, in pertinent part, as follows:
(a) The aggregate number of Securities to which this Schedule 13D
relates is 2,499,252 shares, representing 11.18% of the 22,337,049 shares
outstanding.  This latter number of shares is arrived at by adding the number
of shares reported as being outstanding in the Issuer's most recently filed
Form 10-Q for the quarterly period ended April 1, 2005 (22,142,262 shares) to
the number of shares (194,787 shares) which would be receivable by the
Reporting Persons if they were to convert all of the Issuer's 6% Convertible
Subordinated Debentures  held by them into common shares.  However, at current
market prices it would be uneconomic for any person to convert any of the such
Convertible Notes and that substantially all such Convertible Notes and not
just those held by the Reporting Persons would be converted if it became
economic to do so.  Accordingly, the Reporting Persons believe that the
percentage of beneficial ownership attributable to them under the rules of the
SEC are artificially high and that a more realistic percentage of their
aggregate economic interest, which does not take into account the conversion of
such Convertible Notes, would be 10.41%. The Reporting Persons beneficially own
those Securities as follows:

Securities owned beneficially by each of the foregoing persons. GSI is deemed
to have beneficial ownership of the Securities beneficially owned by Gabelli &
Company.  GBL and Gabelli Partners are deemed to have beneficial ownership of
the Securities owned beneficially by each of the foregoing persons other than
Mario Gabelli and the Foundation.
(b) Each of the Reporting Persons and Covered Persons has the sole
power to vote or direct the vote and sole power to dispose or to direct the
disposition of the Securities reported for it, either for its own benefit or
for the benefit of its investment clients or its partners, as the case may be,
except that  (i) GAMCO does not have authority to vote 52,500 of the reported
shares, (ii) Gabelli Funds has sole dispositive and voting power with respect
to the shares of the Issuer held by the Funds so long as the aggregate voting
interest of all joint filers does not exceed 25% of their total voting interest
in the Issuer and, in that event, the Proxy Voting Committee of each Fund shall
respectively vote that Fund's shares, (iii) at any time, the Proxy Voting
Committee of each such Fund may take and exercise in its sole discretion the
entire voting power with respect to the shares held by such fund under special
circumstances such as regulatory considerations, and (iv) the power of Mario
Gabelli, Marc Gabelli, GBL, and GGCP is indirect with respect to Securities
beneficially owned directly by other Reporting Persons.
		(c) Information with respect to all transactions in the Securities
which were effected during the past sixty days or since the most recent filing
on Schedule 13D, whichever is less, by each of the Reporting Persons and
Covered Persons is set forth on Schedule II annexed hereto and incorporated
herein by reference.
