The new RNAV2 navigation system fitted inside a DPD on STIDD stand at
DSEI 2015 |

The
new RNAV2 Precision Navigation System is an innovative electronic navigation
system for use by combat divers, mounted in the DPD, or dismounted in
seconds for swimming in hand-held mode. In either role, the RNAV2 offers
SOF personnel the unprecedented capability of a navigation tool for precise
clandestine subsea navigation,mine countermeasures, beach reconnaissance,ship-attack,
missions, object identification, etc. The RNAV2 adjustable backlit 8.4” color LCD screen constantly displays the operator’s position on a high resolution moving map display for instantaneous situational awareness. Position accuracy of 0.25% over distance traveled is achieved through a suite of high-accuracy on-board sensors and an optimized Kalman filter. The RNAV2 is powered by an internal BB-2590/U Li-Ion battery which provides system power for 7+ hours or 4.5+ hours when configured with the new 2S Sonar Option also unveiled at DSEI 2015. The 2S Sonar Option for RNAV2 enhances the precision navigation capabilities of the RNAV2, adding high quality forward-looking sonar images to the operator in low- and zero-visibility environments for precise long or short range obstacle avoidance and/or target interrogation. Another new optional equipment for the RNAV2 and DPD is the AP2 Autopilot. It provides exceptional RNAV2 control of the DPD by dynamically adjusting vehicle pitch and heading, automatically keeping the DPD on its programmed or manually-selected course and depth, while accurately compensating for the effects of currents, diver motions, and changes in diver buoyancy. Finally, STIDD introduced a new DPD thruster, the TEC2. According to STIDD, the new thruster provides brute power to maritime special operations forces. Compatible with all DPD models, the TEC2 high efficiency thruster provides a 25% increase in speed over the standard MIK thruster. Available in single or dual configuration (per DPD), the new TEC2 thruster offers a number of innovations including a proprietary magnetically coupled drive, no dynamic seals to maintain, increased diver safety, significantly improved efficiency... |

 The CP2 low drag cargo pod on STIDD Systems stand at DSEI 2015 |
|||
Present
for the first time at DSEI was the new STIDD CP2 Cargo Pod as well. This
low-drag towable capsule provides an additional 12 cubic feet (340L) of
cargo space with minimal additional drag, when towed behind the DPD. Optimized
for minimal drag using advanced CFD (Computational Fluid Dynamics), and
extensively dive-tested under real world conditions, the Cargo POD is
fabricated from marine alloy aluminum and hardcoat anodized for prolonged
corrosion resistance and rugged durability. Neutral buoyancy is provided
by hard-mounted rigid foam volumes in the nose and tail sections. The
21 inch (0.53m) diameter and 92.5 inch (2.4m) length are compatible with
NATO submarine torpedo tubes. The POD weighs 80lbs (36kg) in air, and may be loaded with up to 700lbs (317kg) of neutrally buoyant cargo. The POD is towed from the DPD aft tow point. Horizontal and vertical Stern Planes keep the POD aligned within the shadow of the DPD, resulting in minimal additional drag. An additional Cargo POD may be added to double DPD cargo capacity from 12 cu-ft (340L) to 24cu-ft (680L). |

The STIDD DPD is
the most widely used military-grade underwater mobility platform in
the world. The DPD enables divers to travel farther and faster with
more payload than previously possible with any other diver propulsion
device. Depending on the mission and conditions, operators may need different combinations of speed, range, and payload capacity. STIDD now offers an expanded lineup of 3 different DPD models that will fit any profile. All models have the same proven and reliable standard DPD dimensions and US Navy Certifications: DPD Standard model: » NAVSEA 9310 Certified » Approved for US Navy Use (ANU Listing) » Under contract to USMC, US Army, USSOCOM, and many International SOF Maritime Units DPD Extended Range model: » 200% the range of a standard DPD » Two batteries required » Same dimensions & certification as Standard DPD DPD Thruster XT model: » 33% Faster » Redundant propulsion improves mission safety » Twin high effeciency, low noise direct drive DC thruster motors » Two batteries » Additional towing capacity: easily tows 3 to 4 divers with full load |
