HawkEye 360 has secured additional Series E financing and expanded its presence in European defense markets as ministries increase their use of commercial space-based electronic warfare and signals intelligence services.

The Herndon, Virginia based company announced an additional close of its Series E round, raising approximately 23 million dollars in new capital. The latest tranche includes participation from new investors Ghisallo, Principia Growth, and Sixty Degree Capital, along with continued backing from existing investor Strategic Development Fund (SDF).

Chief Executive Officer John Serafini said the new funding reflects investor confidence in the company's strategy and execution as it scales operations. He noted that HawkEye 360 is advancing its capabilities through the integration of Innovative Signal Analysis (ISA) and continued investment in its signals intelligence platform, which supports mission planning and operations for government partners.

HawkEye 360 plans to use the additional capital to further strengthen its balance sheet and to continue pursuing its strategic growth priorities. These priorities include completing the integration of ISA technologies and teams, enhancing space-based collection and analytics capabilities, and supporting a growing pipeline of defense and intelligence customers.

Chief Financial Officer Craig Searle said the second close demonstrates a disciplined approach to capital formation. He emphasized that the fresh funding provides added flexibility as the company manages growth, continues integrating ISA, and advances its analytics platform in a thoughtful and deliberate way. In parallel with its financing efforts, HawkEye 360 has been selected by a European Ministry of Defense for a multi year electronic warfare program valued at up to 75 million dollars. The program represents an expansion of the company's partnerships with European defense clients and supports long term planning for sovereign defense.

Company executives said the award underscores how European defense organizations are building independent capabilities to monitor and assess complex air defense environments. Andrea Bersan, Vice President of International Business Development and Partnerships, said the size and cadence of the engagement align with European requirements for trusted electronic warfare capabilities that integrate into national defense workflows and support sovereign decision making.

Under the contract, HawkEye 360 will provide a subscription to its Air Defense and GPS Interference Monitoring services. These offerings enable customers to monitor and assess air defense radar activity and GNSS interference across areas of interest, generating an operational picture that complements existing national systems and contributes to broader regional defense awareness.

The company noted that operational use of commercial electronic warfare capabilities in active conflict environments has demonstrated their value in supporting time sensitive decision making. Alex Fox, President HawkEye International, said ministries are scaling their use of space derived signals intelligence to meet evolving defense requirements, and that HawkEye 360 is committed to expanding these capabilities across Europe as nations modernize their intelligence, surveillance, and reconnaissance architectures.
