Merlin Labs Puts a $105 Million Bet on the C-130J’s New Autopilot

The Boston-based startup, now public, is retrofitting existing military and cargo fleets with a single software system, sidestepping the decade-long wait for new aircraft designs.

About Merlin Labs

Published

The software stack is called the Merlin Pilot, and the company’s pitch is simple: you do not need to build a new plane to fly it autonomously. Merlin Labs installs its system in the cockpit of existing aircraft, turning a two-person crew into one, or eventually, into none. It is a bet on retrofitting the world’s existing fleet, a path that has landed the company a prime contract with U.S. Special Operations Command and a spot on the NASDAQ.

Founded in 2019 by CEO Matt George, Merlin has raised over $210 million in private funding and completed a public listing via a SPAC merger earlier this year [investors.merlinlabs.com, April 2026]. The company now trades as MRLN, with a reported $107 million in cash and an expectation to reach $183 million after a recent $80 million PIPE financing [investors.merlinlabs.com, April 2026]. Its headcount sits at roughly 180 employees, according to public data [neuron.com, 2026]. The core technical premise is an aircraft-agnostic autonomy layer, a single software package designed to adapt to any airframe, from a King Air to a C-130J transport plane [merlinlabs.com]. This approach lets Merlin sell into military and commercial cargo operators who cannot afford to wait for a next-generation airframe design.

The retrofit wedge

Merlin’s commercial strategy hinges on a critical constraint in aviation: certification cycles. Designing, building, and certifying a new aircraft takes a decade or more. Merlin’s system, by contrast, is designed as a retrofit kit. It uses existing aircraft sensors and flight controls, overlaying its software to handle navigation, takeoff, landing, and in-flight decisions. The initial human operator remains in the loop as a safety pilot, with the system acting as a highly capable co-pilot before progressing to fully autonomous operations [newatlas.com, 2026].

This wedge has opened doors that would otherwise be closed. The company’s first major partnership was with Dynamic Aviation, covering 55 of its King Air turboprops [TechCrunch, 2021]. More significantly, it secured a $105 million contract ceiling with U.S. Special Operations Command (SOCOM) to bring autonomy to the C-130J fleet, where it serves as the sole prime contractor [insideunmannedsystems.com, February 2026]. In March, Merlin completed the Preliminary Design Review (PDR) for that program, a formal milestone in the Pentagon’s acquisition process [investors.merlinlabs.com, March 2026]. The company has also secured airworthiness approval from the Air Force to install the Merlin Pilot on the KC-135 Stratotanker and is working on a separate $16 million contract for C-130J aircrew workload management [sec.gov, 2025] [washingtontechnology.com, March 18, 2026].

The technical stack

At its core, the Merlin Pilot is a software-defined autopilot. The company describes it as combining “industry standards for safety with highly agile AI” [merlinlabs.com, 2026]. In practice, this means building on established aviation safety architectures,the kind required for certification,while using machine learning for perception and decision-making tasks. The system is not training a neural network to fly from scratch; it is integrating AI modules into a deterministic, safety-critical framework.

The company has tested the system across five distinct aircraft types and conducted real-world flights on commercial routes in Alaska and New Zealand [newatlas.com, 2026]. To accelerate development and validation, Merlin is part of Northrop Grumman’s Beacon autonomous testbed program, using a Scaled Composites Model 437 as a dedicated flying laboratory [sec.gov, 2025]. Partnerships with established aerospace suppliers like Honeywell and GE Aerospace aim to build the “autonomy core” directly into future avionics systems, moving from retrofit to line-fit installations [sec.gov, 2025].

Funding the public path

Merlin’s capital story is one of consistent, large-scale raises focused on a long development runway. The company closed a $105 million Series B in July 2022, led by Snowpoint and Baillie Gifford, bringing its total private funding to $130 million at the time [TechCrunch, July 2022]. Earlier rounds were led by GV and First Round Capital [PERPLEXITY SONAR PRO BRIEF]. In March 2026, it completed a business combination with Inflection Point Acquisition Corp. IV, going public on the NASDAQ. The deal provided approximately $200 million in gross proceeds, including a fully committed PIPE [merlinlabs.com, 2026]. A subsequent $80 million PIPE in April 2026 bolstered the balance sheet for program execution [investors.merlinlabs.com, April 2026].

The public market provides a different kind of fuel. For a capital-intensive business targeting government contracts with long payment cycles, the liquidity and continued access to capital are strategic. The company’s pre-money valuation was set at $800 million ahead of the business combination [sec.gov, 2025].

The competitive airspace

Merlin is not the only company pursuing autonomous flight. Its most direct competitors are firms like Reliable Robotics, which is also retrofitting existing aircraft for autonomy, and Shield AI, which focuses on AI pilots for military aircraft. The competitive landscape turns on three axes: certification progress, government contracts, and partnership depth with legacy aerospace.

  • Certification pace. The race is not to first flight, but to first certified system for commercial use. Merlin’s work in New Zealand, a jurisdiction known for its pragmatic aviation regulator, is a deliberate path to gather flight data and build a certification case [sec.gov, 2025].
  • Contract moat. The SOCOM prime contract for the C-130J is a significant barrier. Once integrated and approved, displacing Merlin from that specific airframe and mission set would be costly and time-consuming for the government.
  • Integration use. Partnerships with Honeywell and GE Aerospace are less about immediate revenue and more about embedding Merlin’s technology into the supply chain for future aircraft. This is a long-term play for line-fit rather than retrofit.

The technical moat is the aircraft-agnostic claim. A system that can be adapted from a small twin-engine turboprop to a four-engine military transport without a full redesign would offer substantial cost and time advantages. The company says it has proven this across hundreds of hours of autonomous flight on multiple platforms [merlinlabs.com].

The scale question

The bet is clear: retrofit today’s fleet faster than anyone can build tomorrow’s. The risks are equally clear, and they are largely about scaling a deeply complex technical and regulatory process.

The technical breakdown is instructive. The Merlin Pilot must interpret sensor data, understand air traffic control instructions, manage aircraft systems, and respond to emergencies,all within the rigid safety margins of aviation. While the AI handles perception and planning, the underlying flight control laws and failure modes must be deterministic and provable. This hybrid approach is sensible, but integrating novel AI into a certified safety-critical system is a frontier problem. A single ambiguous edge case during certification could add years.

Then there is the business model scaling. Military contracts provide validation and early revenue, but the unit economics of retrofitting thousands of commercial cargo aircraft are different. The sales cycle, installation cost, and ongoing support network must be built. A system designed for “any aircraft” must still be tailored and validated for each new type, a process that is faster than a clean-sheet design but not trivial.

Merlin’s answer is to use military contracts to fund the development of a hardened, proven system, then apply it to the commercial market. The next twelve months will test that bridge. Key milestones will be the completion of the Critical Design Review for the C-130J program and the accumulation of enough commercial flight test data in New Zealand to file for type certification. The company has the capital, the contract, and the technical premise. The question is whether it can turn a successful prototype on five aircraft types into a certified product on fifty.
