Arquimea Expands Naval Loitering Munition Capabilities with Acquisition of Perseo Techworks

Arquimea, a prominent player in the loitering munition arena, has made significant strides in enhancing its capabilities by acquiring Perseo Techworks. This strategic decision not only amplifies Arquimea’s portfolio but also marks its entrance into the realm of naval loitering munitions with the introduction of the S-Wise underwater system.

Overview of Recent Developments

Just prior to the DSEI exhibition, Arquimea publicly announced its acquisition of Perseo Techworks. This move was poised to spotlight the S-Wise underwater loitering munition at Arquimea’s display booth. Notably, the S-Wise is not entirely new; it was previously showcased during FEINDEF 2023 in Madrid, where it was presented in collaboration with Navantia and SAES. This partnership emphasized the development of the S-UUV series, which aims to create multiple variants including medium and large models.

The unveiled S-Wise at DSEI closely resembles the earlier S-UUV concept, yet it has evolved into a market-ready product following extensive maritime testing.

Multifunctionality of the S-Wise

While designated as a loitering munition, the S-Wise offers multifaceted operational capabilities. It can serve in various roles, including:

• Suicide Mode: Carrying a lethal payload in traditional loitering munition formats.
• Intelligence, Surveillance, and Reconnaissance (ISR): Engaging in vital reconnaissance tasks.
• Mine Countermeasure (MCM): Functioning effectively in mine detection and neutralization operations.

This adaptability arises from a versatile onboard computer loaded with software suited for both the munitions and ISR operations. By merely swapping the bow section, the S-Wise can accommodate either a warhead or a sophisticated sonar system.

Technical Specifications and Design

The S-Wise boasts impressive dimensions: measuring 2.23 meters in length with a maximum diameter of 0.245 meters. It features a hydrodynamically optimized hull designed via additive manufacturing techniques, utilizing acoustically transparent materials facilitating the integration of sonar systems.

Key Features:

• Versatile Payload Options:

  • Maximum payload capacity exceeds 30 kg, with a volume greater than 30 liters.
  • Options include a 5 kg warhead or sonar systems like the Teledyne BlueView M900/2250.

• Propulsion System:

  • Implements two three-blade counter-rotating screws, enabling stealth configurations and varying mission profiles.
  • Three electric motors deliver up to 6 kW of power, supported by resilient Li-Ion battery technology.

• Performance Metrics:

  • Maximum operational speed exceeds 8 knots.
  • Surface autonomy rated at 85 nautical miles at 2.75 knots.
  • Submerged capabilities include ranges of 80 nautical miles at 3.00 knots and 30 nautical miles at 5.20 knots.

Innovative Navigation and Control Mechanisms

At the heart of the S-Wise lies an advanced navigation and control system, leveraging a Perseo ORA onboard computer with edge computation capabilities. This architecture incorporates:

• A dedicated graphics processing unit for executing artificial intelligence algorithms tailored for automatic target recognition.
• Comprehensive navigation technologies, including a combination of inertial measurement units, geomagnetic devices, and optional Doppler velocity logs.

Integration and Communication

The system facilitates seamless data exchange with other units through sophisticated persistence algorithms. The human operator remains integral to the process, interfacing via a ground control station equipped to communicate through Wi-Fi, LTE/5G, and underwater channels, thus maintaining operational oversight.

Advanced Payload Configurations

The S-Wise allows for diverse expansion based on its deployment role. In the MCM configuration, it can incorporate side-scan and synthetic aperture sonars. Conversely, for the LM/ISR missions, the S-Wise can utilize dedicated wings carrying secondary explosives, significantly enhancing its destructive capabilities.

Mission Planning and Training Tools

Arquimea has also integrated a mission-planning system alongside an advanced training mechanism. This not only prepares personnel for operations but also provides a platform for operational experimentation in realistic environments.

Conclusion: Cost-Effectiveness and Production Advantages

The S-Wise represents a substantial advancement in naval munitions, featuring a design that prioritizes repairability and cost-efficiency. Its production methods allow for decentralized manufacturing, making it an attractive solution for modern naval forces grappling with budget constraints and the need for advanced maritime capabilities.

In a landscape where the efficacy of unmanned technologies is critical, the S-Wise positions Arquimea as a strong contender in the evolving domain of underwater warfare, providing versatile and innovative solutions for future defense strategies.
