Company Background and Mission

Perigee Aerospace was established by a group of young engineers and researchers associated with KAIST, drawing on academic expertise in rocket propulsion, aerospace structures, and systems engineering. The founding team's ambition was to build a homegrown Korean launch capability for small satellites, giving domestic and international customers an alternative to larger, less flexible launch options.

The company's mission centers on democratizing access to space by offering dedicated launch services that allow customers to choose their orbit, launch timing, and mission profile without having to compromise as secondary payloads on shared rockets. This "dedicated smallsat launch" philosophy underpins the company's technical and commercial strategy.

Core Focus: Small Satellite Launch Vehicles

The central activity of Perigee Aerospace is the design, development, testing, and eventual operation of small orbital launch vehicles. Small launch vehicles are optimized to carry payloads in the range of tens to a few hundred kilograms into low Earth orbit and sun-synchronous orbits (SSO), which are commonly used for Earth observation and remote sensing satellites.

Blue Whale Launch Vehicle Family

Perigee's flagship development effort has centered on its "Blue Whale" family of rockets. The naming reflects the company's aspiration to build vehicles that are efficient and capable within their class. The Blue Whale program has included:

• Blue Whale 0.1 / 0.2: Early-stage sounding rockets and technology demonstrators used to validate propulsion systems, structures, and flight control technologies. These smaller vehicles serve as stepping stones toward larger orbital-class rockets, allowing the engineering team to accumulate flight data and refine their designs.

• Blue Whale 1: The company's orbital-class small launch vehicle intended to deliver small satellite payloads into low Earth orbit and sun-synchronous orbits. This vehicle represents the primary commercial product around which Perigee's launch service offering is built.

The Blue Whale vehicles are designed to use liquid propulsion systems, with the company investing in engine development, propellant handling technologies, and lightweight composite structures to keep the vehicles efficient and cost-competitive.

Propulsion and Technology Development

A key part of Perigee's work involves in-house development of rocket propulsion systems. Rocket engines are among the most technically demanding components of any launch vehicle, and the company has focused significant engineering resources on:

• Liquid rocket engine design and testing, including combustion chamber, injector, and turbomachinery development.

• Cryogenic and advanced propellant systems, which are essential for achieving the performance needed to reach orbit.

• Lightweight structures and materials, including composite tanks and airframe components that reduce vehicle mass and improve payload capacity.

• Avionics, guidance, navigation, and control (GNC) systems that manage the rocket's flight path and ensure accurate payload delivery.

The company has conducted a series of ground tests and flight tests of its propulsion systems and smaller demonstration vehicles as part of a phased development approach, incrementally proving out the technologies required for full orbital flight.

Launch Services

The commercial product Perigee ultimately aims to deliver is dedicated launch services for small satellite operators. This service model is built around several value propositions:

• Dedicated missions: Customers can book an entire rocket for their payload rather than sharing with unrelated satellites, giving them control over the target orbit and deployment sequence.

• Orbital flexibility: The ability to select specific orbits, including sun-synchronous orbits favored by Earth observation missions.

• Schedule responsiveness: Faster and more flexible launch scheduling compared to waiting for a slot on a large rideshare mission.

• Cost efficiency for smallsats: Pricing tailored to the small payload market, making dedicated launch economically viable for operators of small and microsatellites.

Perigee has also explored launch site arrangements to support its operations, which is an important consideration for any launch provider since access to a suitable launch range with appropriate safety corridors and orbital trajectories is essential.

Market Position and Industry Context

Perigee Aerospace operates in the competitive and rapidly evolving small satellite launch sector. Globally, this market has attracted numerous private companies seeking to serve the surge in small satellite deployments. Within South Korea, Perigee is notable as one of the earliest privately funded launch-vehicle startups, complementing the government's own space launch efforts such as the KSLV (Korea Space Launch Vehicle) program managed through national institutions.

The company benefits from South Korea's strong engineering talent base, its growing NewSpace ecosystem, and increasing national interest in developing sovereign and commercial space capabilities. By focusing on the small launcher niche, Perigee aims to carve out a distinct position separate from heavy-lift national rockets, targeting commercial and institutional customers who need dedicated smallsat access.

Summary

Perigee Aerospace is a South Korean space technology company dedicated to the development of small satellite launch vehicles and the provision of dedicated launch services for the smallsat market. Rooted in KAIST's engineering expertise and based in Daejeon, the company has pursued a phased development strategy through its Blue Whale rocket family, progressing from sounding rockets and technology demonstrators toward an orbital-class small launcher. Its core competencies span liquid rocket propulsion, lightweight aerospace structures, avionics, and flight control systems. As part of South Korea's emerging private space industry, Perigee Aerospace aims to provide flexible, affordable, and dedicated access to low Earth orbit for satellite operators around the world.
