Gallon is a recoverable and reusable orbital class rocket designed to carry Small, Micro and Cubesatellites to LEO. The vehicle has multiple fairing options based on payload requirements and engine configurations based on mission profile.
The Booster stage can perform a set of maneuvers while reentry descent and landing, with the the upper stage being recovered using partially guided parachutes.

Second and third stages designed for demanding, mid-lift missions to Low Earth Orbit (LEO), Sun Synchronous Orbit (SSO) and Geosynchronous Transfer Orbit (GTO).
Indegeniously developed by BAAS, the Joules-3S is optimized to operate in the vacuum of space. Its high thrust and high specific impulse enable Gallon's upper stage to accomplish a wide variety of missions.
Four actuated grid surfaces for attitude and stability adjustments during the booster's descent and landing.
Designed for reuse and minimal maintenance in between flights.
Designed to fly with flexible engine configurations, variable number of engines based on payload requirements and mission profiles; for reliable and efficient launches.
Aft module houses four hydraulically-actuated legs to support and secure the booster during landing.
Located at Sriharikota, the Satish Dhawan Space Centre (SDSC SHAR) serves as India’s primary satellite launch site, supporting a range of orbital and sub-orbital missions. First Launch Pad (FLP) and Second Launch Pad (SLP) are located at Sriharikota, Andhra Pradesh, within the Satish Dhawan Space Centre. Operational since 1971, it is India's primary satellite launch site and has facilitated numerous historic missions.
The complex supports launch vehicle integration, payload assembly, propellant loading, and mission control operations. FLP and SLP has been the site of landmark launches, including the first Polar Satellite Launch Vehicle (PSLV) mission and several GSLV missions that have placed satellites in orbit for both India and global customers. It stands as a cornerstone of India's space exploration program.
Gallon will lift off. Following separation, the booster will autonomously descend to a landing platform, while the second stage will propell into space. After the fairing separates, payload will be safely delivered into orbit.
A reusable rocket is purpose-built to deliver high volume and mass to desired destination, BAAS is purposed to develop advanced reusable launch vehicles for our long-term vision — where heavy industries are easily and affordably transported into space to preserve the lands.
