Item 1. Security and Issuer.

This Amendment No. 4 (the "Amendment") amends the Statement of Beneficial Ownership on Schedule 13D, originally filed with the Securities and Exchange Commission (the "Commission") on November 23, 2005, and as further amended on January 17, 2006, July 24, 2006 and December 13, 2006 (the "Schedule 13D") by Wynnefield Partners Small Cap Value, L.P. (the "Partnership"), Wynnefield Partners Small Cap Value, L.P. I (the "Partnership-I"), Wynnefield Small Cap Value Offshore Fund, Ltd. (the "Fund"), Wynnefield Capital Management, LLC ("WCM") and Wynnefield Capital, Inc. ("WCI"), with respect to shares of common stock, $0.10 par value (the “Common Stock”), of The Allied Defense Group, Inc., a Delaware corporation with its principal executive offices located at 8000 Towers Crescent Drive, Vienna, VA 22182 (the "Issuer"). In addition to the Wynnefield Group, this Amendment is filed on behalf of Nelson Obus (“Mr. Obus”) and Joshua Landes (“Mr. Landes” and, collectively with Partnership, Partnership-I, Fund, WCM, and Mr. Obus, the "Wynnefield Group"). Unless specifically amended hereby, the disclosures set forth in the Schedule 13D shall remain unchanged.

ITEM 5. INTERESTS IN SECURITIES OF THE ISSUER.

The response to Item 5 is hereby amended and restated in its entirety as follows:

(a) - (c) As of December 19, 2006, the Wynnefield Group beneficially owned in the aggregate 587,235 shares of Common Stock, constituting approximately 9.7% of the outstanding shares of Common Stock (the percentage of shares owned being based upon 6,034,558 shares outstanding on September 30, 2006, as set forth in the Issuer's most recent report on form 10-Q for the period ended September 30, 2006 filed with the Securities and Exchange Commission on November 14, 2006). The following table sets forth certain information with respect to shares of Common Stock beneficially owned directly by the Wynnefield Group members listed:

Name	Number of Shares	Approximate Percentage of Outstanding Shares
Partner*	141,500	2.3%
Partnership-I*	222,100	3.7%
Fund**	223,635	3.7%

* WCM has an indirect beneficial ownership interest in these shares of Common Stock.

** WCI has an indirect beneficial ownership interest in these shares of Common Stock.


CUSIP No. 019118108		13D/A	Page 10 of Pages 11

WCM is the sole general partner of the Partnership and Partnership-I and, accordingly, may be deemed to be the indirect beneficial owner (as that term is defined under Rule 13d-3 under the Exchange Act) of the shares of Common Stock that the Partnership and Partnership-I beneficially own. WCM, as the sole general partner of the Partnership and Partnership-I, has the sole power to direct the voting and disposition of the shares of Common Stock that the Partnership and Partnership-I beneficially own.

Messrs. Obus and Landes are the co-managing members of WCM and, accordingly, each of Messrs. Obus and Landes may be deemed to be the indirect beneficial owner (as that term is defined under Rule 13d-3 under the Exchange Act) of the shares of Common Stock that WCM may be deemed to beneficially own. Each of Messrs. Obus and Landes, as a co-managing member of WCM, shares with the other the power to direct the voting and disposition of the shares of Common Stock that WCM may be deemed to beneficially own.

WCI is the sole investment manager of the Fund and, accordingly, may be deemed to be the indirect beneficial owner (as that term is defined under Rule 13d-3 under the Exchange Act) of the shares of Common Stock that the Fund beneficially owns. WCI , as the sole investment manager of the Fund, has the sole power to direct the voting and disposition of the shares of Common Stock that the Fund beneficially owns.

Messrs. Obus and Landes are the principal executive officers of WCI and, accordingly, each of Messrs. Obus and Landes may be deemed to be the indirect beneficial owner (as that term is defined under Rule 13d-3 under the Exchange Act) of the shares of Common Stock that WCI may be deemed to beneficially own. Each of Messrs. Obus and Landes, as a principal executive officer of WCI, shares with the other the power to direct the voting and disposition of the shares of Common Stock that WCI may be deemed to beneficially own.

Beneficial ownership of shares of Common Stock shown on the cover pages of and set forth elsewhere in this Amendment for each of the members of the Wynnefield Group assumes that they have not formed a group for purposes of Section 13(d)(3) under the Securities Exchange Act of 1934, and Rule 13d-5(b)(1) promulgated thereunder. If the members of the Wynnefield Group were deemed to have formed a group for purposes of Section 13(d)(3) and Rule 13d-5(b)(1), the group would be deemed to own beneficially (and may be deemed to have shared voting and dispositive power over) 587,235 shares of Common Stock, constituting approximately 9.7% of the outstanding shares of Common Stock (the percentage of shares owned being based upon 6,034,558 shares outstanding on September 30, 2006, as set forth in the Issuer's most recent report on form 10-Q for the period ended September 30, 2006 filed with the Securities and Exchange Commission on November 14, 2006).

The filing of this Amendment and any future amendment by the Wynnefield Group, and the inclusion of information herein and therein with respect to Messrs. Obus and Landes, shall not be considered an admission that any of such persons, for the purpose of Section 13(d) of the Exchange Act, are the beneficial owners of any shares in which such persons do not have a pecuniary interest.

To the best knowledge of the Wynnefield Group, except as described in this Amendment, none of the Wynnefield Group, any person in control (ultimately or otherwise) of the Wynnefield Group, any general partner, executive officer or director thereof, as applicable, beneficially owns any shares of Common Stock, and there have been no transactions in shares of Common Stock effected during the past 60 days by the Wynnefield Group, any person in control of the Wynnefield Group (ultimately or otherwise), or any general partner, executive officer or director thereof, as applicable; provided, however, certain investment banking affiliates of the Wynnefield Group may beneficially own shares of Common Stock, including shares that may be held in discretionary or advisory accounts with the Wynnefield Group; and the Wynnefield Group, directly or in connection with such discretionary or advisory accounts, may acquire, hold, vote or dispose of Common Stock, including transactions that may have occurred in the past 60 days.

The Wynnefield Group has made purchases of shares of Common Stock during the last 60 days, as follows:

Name	Date	Number of Shares	Price Per Share
Partner*	December 15, 2006	16,000	$16.71*
Partnership-I*	December 15, 2006	22,000	$16.71*
Fund**	December 15, 2006	26,000	$16.71*
* Private placement

(d) No person, other than each of the members of the Wynnefield Group referred to as the direct beneficial owner of the shares of Common Stock set forth in this response to Item 5, has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, such shares of Common Stock.

(e) Not applicable.
