We’re excited to introduce the REMUS 300: our newest small-class Unmanned Underwater Vehicle (UUV). Combining maximum flexibility with portability, the REMUS 300 is designed to meet a wide variety of mission needs. Key features include:
Go Deeper Without Compromising Portability
We based the 7.5 inch diameter hull design off of the already trusted REMUS 100 UUV. The hull sections have been redesigned for increased strength, allowing the vehicle to reach depths up to 305 meters (1000 feet). With the added modularity, the REMUS 300 can be reconfigured for different missions, from an 80 pound expeditionary configuration to a 130 pound long endurance configuration. Portability is one of the most important features users want, and with the 7.5 inch diameter we have made sure the REMUS 300 is flexible and can conform to different mission requirements.
We’ve repackaged our electronics and payloads to increase modularity with the REMUS 300. Blind-mate end caps and toolless band clamps allow for field-swappable modules. A removeable 1 terabyte hard drive allows you to quickly offload data. Reconfiguring your REMUS on the go for increased endurance or an additional payload has never been easier.
Flexible Energy Options:
REMUS 300 has options for 1.5, 3.0 or 4.5 kWh lithium-ion battery sections that correspond to up to 12, 19 or 29 hours of endurance. Blind-mated end caps conform to IP-X4 standards allowing for field expedient battery exchange during missions. Choose the energy package that best matches your mission requirements to maximize your efficiency. As other energy options mature, they can easily be added to the REMUS 300 in a neutrally buoyant module.
The REMUS 300 conforms to Modular Open Systems Architecture (MOSA) and Unmanned Maritime Autonomy Architecture (UMAA) standards with a Data Distribution System (DDS) open architecture platform. This open architecture is the backbone of our REMUS Technology Platform, allowing for rapid integration of new modules and software and decreasing risk with development, schedule and cost for customers. Hydroid is also developing a Software Development Kit (SDK) and Hardware Development Kit (HDK) for third-party software and payload development.
HYFleet Graphic User Interface:
HYFleet is a new graphic user interface that will be delivered with REMUS 300 UUVs. This intuitive platform has been redesigned from the ground up and can be cloud-based, server-based or software-based. With automatic mission validation and drag-and-drop functionality, mission planning is fast and simple. HYFleet also enables multiple vehicles to be monitored at the same time. HYFleet will be delivered alongside our current Vehicle Interface Program (VIP) so that you can choose to use either interface.
The open architecture and modularity of the REMUS 300 gives the user maximum flexibility when it comes to outfitting their vehicle for mission requirements. Add a larger energy module for longer missions, or a smaller one for fast, expeditionary missions. Include a payload for additional data collection or leave it off to save energy. The REMUS 300 is one vehicle, but it can be configured for many different missions.
The 7.5 inch diameter hull was a calculated choice for us. The larger the hull, the heavier the UUV. The trend with sensors and payloads is toward more compact, efficient systems that fit well within our platform. We have a suite of sensors and payloads on the roadmap for REMUS 300, giving the user the options they need in a compact, two-man portable system. With over 400 7.5 inch diameter REMUS 100 systems already in use worldwide, we’re excited to be able to offer a deeper variant while still providing the portability that users need.
The REMUS Technology Platform is available on all our new generation REMUS UUVs. It consists of advanced core electronics that have been redesigned for efficiency and performance. All new generation vehicles are open architecture, which means integrating new payloads, sensors and algorithms is easier and more economical. The REMUS technology platform is scalable across all vehicle classes, providing the consistency and reliability users want across our family of systems.

All Hydroid UUVs have core systems designed to monitor the status and operation of essential components. Health monitoring includes batteries, motors, sensors and communications as well as conditions such as depth or water ingress. If an abnormality is detected, then an alarm is raised. During supervised missions this will be transmitted to the operator enabling them to decide if the vehicle should return from its mission. When the vehicle is operating autonomously, the response to an alarm is determined by the preselected response listed in the mission plan. This could include an emergency abort to preserve vehicle security.
Operators can monitor the UUV’s progress and status via an acoustic link. This also enables amendments to the mission plan to be sent to the vehicle along with position updates if required. The Ranger positioning systems provide acoustic aiding to the on-board IMU and DVL equipment to make the realtime position solution as accurate as possible. When the UUVs are on the surface, they can communicate via Wi-Fi or radio with the operator. They are also equipped with GPS receivers to update the IMU position with the most accurate information available.
To assist with emergency localization and recovery operations, the UUVs can be equipped with emergency radio beacons, strobe lights and satellite communications. In the event of an emergency ascent, the position and status of the vehicle can be sent via the Iridium network to the operators and home base simplifying postemergency localization. If two-way satellite communication is enabled, a revised mission plan can be sent to the vehicle from anywhere in the world.
