Defense tech funding and contracts roundup: June 2026

New contracts awarded and funding rounds closed in June 2026, pulled directly from the index's contract award dates and cap table round dates, not editorial review timestamps. See the May 2026 roundup for last month's edition.

Contracts

• HawkEye 360 — International Partner RF Analytics Contracts, $101M, multiple international partners, firm-fixed-price (services), awarded 2026-06-01.

Funding and public-market events

• SpaceX — IPO, $75B raised at a $1.77T valuation, closed June 2026. By far the largest liquidity event in the index's history, and a reference point for how a defense-adjacent company can exit outside the acquisition-by-a-prime path discussed in why defense tech valuations lag SaaS multiples.
• Mach Industries — Series C, $300M at a $1.8B valuation, closed June 2026.
• Relativity Space — Series E, $800M, closed June 2026 (valuation undisclosed).

What stands out

SpaceX's IPO is an outlier by size, not a signal about typical defense tech liquidity — most companies in the index exit, if at all, through acquisition by a prime rather than a public listing of this scale. Mach Industries' Series C and Relativity Space's Series E are the more representative venture-stage data points from this window.
