Bluebird Satellites on Defense Radar: Why ASTS Stock Surged 291.7% and Could Reshape Secure Communications

Like the bluebird symbolizing hope and resilience, AST SpaceMobile’s BlueBird LEO satellites represent a breakthrough in defense communication infrastructure. The company (ASTS) has emerged as a critical player in military-grade connectivity, with its direct-to-smartphone satellite network addressing a fundamental vulnerability in modern defense operations.

The Defense Communication Gap That ASTS Is Filling

Traditional ground-based networks become unreliable in remote regions, over oceans, and during natural disasters—exactly where defense forces need connectivity most. AST SpaceMobile’s BlueBird constellation solves this through satellites that transmit directly to standard mobile phones without requiring specialized equipment. This capability transforms how troops coordinate, emergency responders communicate, and logistical operations function when terrestrial infrastructure fails.

The U.S. government has recognized this value, awarding ASTS multiple defense and government contracts. These awards signal that satellite-based resilient communications are transitioning from theoretical advantage to practical military infrastructure. With escalating U.S. defense spending on hypersonics and rapid response systems, space-based connectivity has become essential for maintaining command and control in contested environments.

How ASTS Stacks Up Against Rivals

The competitive landscape includes Globalstar (GSAT) and Viasat (VSAT), each pursuing different satellite strategies.

Globalstar partnered with SpaceX to deploy new satellites through 2026, recently introducing its RM200M—a two-way IoT device enabling global connectivity via LEO networks. This positions Globalstar as a leader in IoT-focused satellite applications.

Viasat operates high-capacity communication satellites for broadband, military communications, and maritime connectivity. The company’s ViaSat-3 F2 satellite expansion targets broadband resilience, competing directly in the secure military communications segment where ASTS is also focused.

ASTS differentiates through its smartphone-direct approach, which requires no additional hardware for end users—a significant advantage for rapid deployment and operational flexibility.

Market Performance Reveals Investor Confidence

ASTS shares surged 291.7% over the past 12 months, substantially outpacing the industry’s 24.4% growth. This dramatic appreciation reflects market recognition of the company’s defense applications and space resilience narrative.

However, valuation metrics tell a cautionary tale. ASTS trades at a forward price-to-sales ratio of 122.6—far exceeding industry averages. This premium pricing embeds significant growth expectations into the current share price.

Earnings estimates have adjusted downward recently. The Zacks Consensus Estimate for 2025 bottom-line performance revised to a loss of $1.06 (down 8.16% in 60 days), with 2026 projected losses of $0.74 (down 8.8% over the same period). The company currently holds a Zacks Rank #3 (Hold) rating, suggesting analyst caution despite the stock’s strong appreciation.

The Space Defense Megatrend Remains Compelling

Despite valuation concerns, the underlying defense communication opportunity is genuine. Global commercial space launches are accelerating as satellite operators demand quicker deployment cycles and flexible mission architectures. Nations worldwide are prioritizing space resilience and secure connectivity—trends that directly benefit operators like AST SpaceMobile.

The question for investors isn’t whether satellite defense communications matter—they clearly do. It’s whether current valuations adequately price in execution risks, timeline uncertainties, and competition from well-funded rivals.
