I (the "Partnership-I"), Wynnefield Capital Management, LLC ("WCM"), Wynnefield Capital, Inc. ("WCI" or "Wynnefield Capital"), the Wynnefield Capital, Inc. Profit Sharing Plan (the "Plan"), Nelson Obus ("Mr. Obus") and Joshua Landes ("Mr. Landes" and, collectively with the Partnership, the Fund, the Partnership-I, WCM, WCI, the Plan and Mr. Obus the "Wynnefield Reporting Persons"), with respect to the shares of 12% Cumulative Exchangeable Redeemable Preferred Stock, par value $0.01 per share (the "Preferred Shares", “Preferred Stock” or “TLSRP”), of Telos Corporation, a Maryland corporation with its principal executive offices located at 19886 Ashburn Road, Ashburn, Virginia 20147-2358 (“Telos”, the “Company” or the "Issuer"). All defined terms refer to terms defined herein or in the Wynnefield Schedule 13D. The information contained in this Amendment is as of the date hereof, unless otherwise expressly provided herein.

The securities reported in this Statement as directly beneficially owned by the Wynnefield Reporting Persons were acquired with funds of $2,709,723 (including brokerage commissions).

CUSIP No. 87969B200 13D/A Page 11 of 15 pages

ITEM 4. PURPOSE OF TRANSACTION.

Item 4. "Purpose of Transaction." appearing in the Wynnefield Schedule 13D is supplemented by adding the following statement from Wynnefield Capital to the end of such item:

Wynnefield Capital and the other Wynnefield Reporting Persons congratulate Telos on recently receiving the go ahead from the Air Force’s NETCENTS-2 Program Office to compete in both full and open and small business competition categories. Following an 18-month protest delay, Telos is now ready to support government customers under the contract which is a preferred vehicle for acquisitions by agencies throughout the federal government.

The Wynnefield Reporting Persons purchased additional Preferred Shares of Telos in May and July of 2015 because of their continuing belief in the inherent value of the Preferred Shares.  The Wynnefield Reporting Persons intend to continue their efforts to have the FULL value of their Preferred Shares realized through the redemption of their principal and all accrued dividend arrearages, and may contact Telos as part of these efforts.  Although the Wynnefield Reporting Persons continue to hear nothing from the Telos management regarding its liabilities owed to the holders of Preferred Shares, the Wynnefield Reporting Persons remain open to engaging in a serious discussion leading to the FULL redemption of Preferred Shares including principal and all arrearages. 

The Wynnefield Reporting Persons note that the word “ages” is contained within the word “arrearages” -- as in the Preferred Shareholders have waited “AGES” to receive the payments due them from Telos.  Furthermore, the Wynnefield Reporting Persons believe Telos is entering a period where the full value of the Company will be evident to strategic buyers and allow both the Preferred Shareholders and other Company equity holders to benefit greatly from a sale of the Company.

CUSIP No. 87969B200 13D/A Page 12 of 15 pages

As of the date of this Amendment and other than as set forth in this Item 4, the Wynnefield Reporting Persons do not have any current plans, proposals or negotiations that relate to or would result in any of the matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Wynnefield Reporting Persons intend to review critically their investment in the Issuer on a continuing basis, and to the extent permitted by law, may seek to engage in discussions with other shareholders and/or with management and the Board of Directors of the Issuer concerning the business, operations or future plans of the Issuer. Depending on various factors including, without limitation, the Issuer’s financial position, the price levels of the shares of the Preferred Stock or the Issuer’s other securities, conditions in the securities markets and general economic and industry conditions, the Wynnefield Reporting Persons may, in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, purchasing additional shares of Preferred Stock or the Issuer’s other securities, selling shares of Preferred Stock or the Issuer’s other securities, engaging in short selling of or any hedging or similar transaction with respect to the Preferred Stock or the Issuer’s other securities, and taking any other action with respect to the Issuer, the Preferred Stock or any of its other securities in any manner permitted by law or changing its intention with respect to any and all matters referred to in paragraphs (a) through (j) of Item 4.

ITEM 5. INTERESTS IN SECURITIES OF THE ISSUER.

Item 5. "Interests in Securities of the Issuer." appearing in the Wynnefield Schedule 13D is supplemented by adding the following disclosure to the end of such item:

(A) - (C) As of July 17, 2015, the Wynnefield Reporting Persons beneficially owned in the aggregate 492,465 shares of Preferred Stock, constituting approximately 15.5% of the outstanding shares of Preferred Stock (the percentage of shares owned being based upon a total of 3,185,586 shares outstanding on March 31, 2015, as set forth in the Issuer's most recent report on Form 10-Q for the quarter ended March 31, 2015 filed with the Commission on May 15, 2015). The following table sets forth certain information with respect to shares of Preferred Stock directly beneficially owned by the Wynnefield Reporting Persons members listed:

NAME	NUMBER OF SHARES	APPROXIMATE PERCENTAGE OF OUTSTANDING SHARES
Partnership*	144,319	4.5%
Partnership-I*	226,792	7.1%
Fund**	106,354	3.3%
Plan**	15,000	0.5%

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

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

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 Preferred Stock that the Partnership and Partnership I directly 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 Preferred Stock that the Partnership and Partnership I directly 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 Preferred Stock that WCM may be deemed to beneficially own. Each of Messrs. Obus and Landes, as co-managing members of WCM, has the power to direct the voting and disposition of the shares of Common Stock that WCM may be deemed to beneficially own.

(Page 12 of 15 pages)

CUSIP No. 87969B200 13D/A Page 13 of 15 pages

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 Preferred 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 Preferred Stock that the Fund beneficially owns. WCI, as the sole investment manager of the Plan, has a beneficial ownership interest in the shares of Preferred Stock that the Plan 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 Preferred 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 Preferred Stock that WCI may be deemed to beneficially own.

Beneficial ownership of shares of Preferred Stock shown on the cover pages of and set forth elsewhere in this Amendment for each of the Wynnefield Reporting Persons assumes that they have not formed a group for purposes of Section 13(d)(3) under the Exchange Act, and Rule 13d-5(b)(1) promulgated thereunder. If the members of the Wynnefield Reporting Persons 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) 492,465 shares of Preferred Stock, constituting approximately 15.5% of the outstanding shares of Preferred Stock (the percentage of shares owned being based upon 3,185,586 shares outstanding on March 31, 2015, as set forth in the Issuer's most recent report on Form 10-Q for the quarter ended March 31, 2015, filed with the Commission on May 15, 2015).

The filing of this Amendment and any future amendment by the Wynnefield Reporting Persons, and the inclusion of information herein and therein with respect to WCM, WCI and Messrs. Obus and Landes, shall not be considered an admission that any of such persons, for the purpose of Section 16(b) of the Exchange Act, are the beneficial owners of any shares in which such persons do not have a pecuniary interest. Each of WCM, WCI and Messrs. Obus and Landes disclaims any beneficial ownership of the shares covered by this Schedule 13D.

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