General Dynamics, the company showcased their cross-domain multi-platform UUV through a theater simulating warfare planning tool. Through the utilization of this simulation, they showed a Littoral combat ship along with two unmanned underwater vehicles. The goal of this exercise was to demonstrate the communication speed between the operator and the UUV. James Langevin, D-R.I., ranking member on the House Armed Services Committee’s subcommittee on emerging threats, stated in regard to this exercise "What this is all driving to is for the warfare commander to be able to make the decisions that are based on what he thinks is high-confidence input quicker than his adversary can," he said. "That’s the goal — we want to be able to … let them make warfare-related decisions quicker than anybody else out there." These exercises were conducted to showcase the applications of unmanned underwater vehicles within the military community, along with the innovations each company created to better suite these specific mission types. Film uses UUVs were also used to film a recent National Geographic documentary called "The Dark Secrets" of the Lusitania, the British ocean liner that the Germans sank during World War 1. To capture footage of the wreckage, the camera crew used a combination of submarines, remotely operated underwater vehicles (ROUVs) and underwater suits called Newtsuits. Argo, a UUV developed by the Woods Hole Oceanographic Institute (WHOI), helped find the wreckage of the Titanic and was equipped with a set of television cameras to capture views of the ship. The vehicle had the capability to capture wide-angle film and zoom in for close views of the wreckage. Footage captured by Argo was included in the 1986 National Geographic documentary Secrets of the Titanic that details an expedition led by Dr. Robber Ballard and lets viewers take a closer look at the wreckage of the ship. Deep-sea exploration and research Unmanned underwater vehicles can be used for deep-sea exploration and research. For example, remotely operated vehicles have been used to collect samples from the sea-floor to measure its microplastics-contents, to explore the deep-sea fauna and structures and discovering new underwater species. UUVs are commonly used in oceanic research, for purposes such as current and temperature measurement, ocean floor mapping, and Hydrothermal vent detection. Unmanned underwater vehicles utilize seafloor mapping, bathymetry, digital cameras, magnetic sensors, and ultrasonic imaging. The Woods Hole Oceanographic Institution employs a vehicle called the Sentry, which is designed to
