Introducing the Esquire-Class

In July, 2017, the U.S. Navy released an RFI seeking conceptual designs for a small surface combatant, the future Guided Missile Frigate, FFG(X). The ship's primary role would be to provide support/relief to larger combatants during conflict and operations other than war, and to augment battlespace awareness ("extend the tactical grid") by establishing independent sensor networks in high threat areas utilizing both onboard and unmanned systems. In February, 2018, the Navy narrowed the design field to five contenders - Austal, Fincanteri, General Dynamics, Lockheed Martin, and Huntington Ingalls - with an RFP expected sometime in 2019 and contract award in 2020.

While the need for a new surface combatant is open to debate, we can be certain that threats to our naval forces will continue to evolve and proliferate. We can also be certain that these threats will be increasingly unmanned and autonomous, requiring innovative and potentially disruptive countermeasures in order to defeat them. The U.S. Navy must remain well ahead of the curve as potential adversaries acquire ever-smaller and potent weapons and weaponized unmanned systems.

Thus, as the Navy moves forward with plans for a new guided missile frigate, we believe there is also a need for a first generation unmanned, autonomous microfrigate whose role it is to augment sea control and maritime security operations by enhancing battlespace awareness and, when necessary, joining the fight, with a particular emphasis on engaging and defeating the growing array of unmanned, autonomous micro-threats clouding the battlespace.

Microfrigates could be produced in far greater numbers, at a faster rate, and at a markedly lower cost than FFG(X).

  • The proposed FFG(X) procurement profile currently calls for a single hull in 2020 and 2021, and two per year during the following nine years, each at a price of $950 million.

  • At an estimated price tag of $50 million per hull, approximately 20 Esquires could be constructed for the cost of a single FFG(X). This is, of course, only a fraction of the total cost savings, as each FFG(X) will also incur substantial manpower, fuel, maintenance, and other operating costs during its life cycle.

A networked flotilla of autonomous microfrigates would greatly reduce the demands upon, and the threat to, high end manned combatants.

  • With its fully integrated UAV and UUV payloads, the Esquire-class is an ideal platform to augment ASW, MCM, EMW and ISR operations, providing wide operating coverage and extending the tactical grid well beyond the horizon.

  • As a semi-autonomous, unmanned platform, microfrigates can operate in high-threat areas without risking human lives.

  • While there are uncertainties and potential dangers surrounding autonomy in weapons systems, these must be weighed against the growing threat posed by peer competitor navies, and even the growing naval power of regional actors, rogue states, and nonstate organizations.

In addition to providing sensor augmentation, the microfrigate is also a fighting ship, fully capable of conducting air defense, undersea warfare, surface warfare, and strike warfare against current and emerging micro threats.

  • The technologies necessary to develop robust micro air and sea combatants are cheap and readily available, enabling not only near-peer competitors, but smaller, cash-strapped players to fashion their own potent micronaval capability.

  • The Esquire's arsenal of vertically-launched nanomissiles and swarming UAVs, as well as self-guided nanoprojectiles and directed energy weapons can engage both surface and air targets at close-in or standoff ranges.

  • Microtorpedos can engage an array of undersea threats, including unmanned vehicles, enemy torpedos, mines, and seabed infrastructure.

  • Stern-launched Strikepods of Atom-class microsubmarines can conduct a range of offensive operations, such as electonic warfare and mining, engage enemy surface and undersea vehicles, or target undersea infrastructure.

A Vessel Whose Time Has Come

With the prospect of great power conflict returning to the fore, along with a renewed emphasis on sea control, and with this occuring at a time of increasingly strained defense budgets, the U.S. Navy should strongly consider procuring an unmanned microfrigate as an effective, low-cost force multiplier to offset the growing naval power of our adversaries.

We therefore submit for the Navy's consideration, the Esquire-class Microfrigate.

Stats:

Length: 15.5 meters (51 ft)
Beam: 5 meters (16.5 ft)
Height: 3.5 meters (Above the water line)
Displacement: 30 - 35 tons (Load dependent)
Draft: 1.5 - 2 meters (5 - 6.5 ft)

Power and Propulsion

A 600-hp turbo microdiesel engine powers dual axial-flow micro waterjets providing precision maneuvering and efficient, high-powered thrust, propelling the Esquire-class at speeds in excess of 40 kts. (The Block II Esquire is slated to feature a Low Energy Nuclear Reactor (LENR) similar to the microreactor found in the Atom-class microsubmarine, which will provide higher energy output, as well as unlimited range and endurance.)

The microdiesel also powers a cutting edge 175 kW microturbine to provide power to shipboard systems.

Sensors & Communications

The Esquire-class is equipped with a wide range of cutting-edge electomagnetic and acoustic sensors, providing unmatched battlespace awareness above, on, and below the sea.

  • AN/SPY-1m MicroAegis Integrated Combat System
  • 2 AN/SLQ-m Electronic Warfare Antennae
  • 2 AN/SPG-m Fire Control Radar
  • AN/SPS-67-m Surface Search and Navigation Radar
  • AN/SQR-m Multi Function Towed Sonar Array
  • AN/SQS-m Bow Sonar Array
  • AN/SLQ-m Electronic Warfare Suite
  • UHF/VHF/SATCOM Antennae
  • High definition video

Weapons & Countermeasures

  • The Mark 45 Mod M 2.5 inch deck gun provides surface, air, and land attack capabilities against small and soft targets using both guided and unguided nanomunitions.
