**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Class A Common Stock, par value $0.0001 per share

**(b) Name of Issuer:**
BlackSky Technology, Inc.

**(c) Address of Issuer's Principal Executive Offices:**
2411 Dulles Corner Park, Suite 300, Herndon, VA, 20171

This Amendment No. 3 (this "Amendment No. 3") amends and supplements the Schedule 13D originally filed by the Reporting Persons with the Commission on September 20, 2021, as it has been amended by Amendment No. 1 filed with the Commission on April 20, 2024 and Amendment No. 2 filed with the Commission on November 12, 2024 (collectively, the "Original Schedule 13D"). The agreement among the Reporting Persons to file jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Act is attached to the Original Schedule 13D as Exhibit 1. This Amendment No. 3 is being filed to update the aggregate percentage of the Common Stock owned by the Reporting Persons due to dilution caused by the Issuer's sales of additional shares of its Common Stock from time to time since the date of the filing of Amendment No. 2 and not in connection with a disposition of any shares by the Reporting Persons. Such dilution resulted in a decrease of over one percent (1%) in the aggregate percentage ownership reported by the Reporting Persons in Amendment No. 2. Only those items that are hereby reported are amended; all other items reported in the Original Schedule 13D remain unchanged. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable. Capitalized terms not defined in this Amendment No. 3 have the meanings ascribed to them in the Original Schedule 13D.

**Item 5. Interest in Securities of the Issuer**

**(a)**
See Items 7-11 and 13 of the cover pages of this Amendment No. 3 for each Reporting Person and the corresponding comments.

**(b)**
See Items 7-11 and 13 of the cover pages of this Amendment No. 3 for each Reporting Person and the corresponding comments.

**(c)**
Except as reported in this Amendment No. 3, none of the Reporting Persons has effected any transactions in the Issuer's securities within the past 60 days.
