More than 30 fragments of the submarine were also lifted to the surface. Deep-Ocean Film Work The MIR submersibles opened a new page in the history of deep-ocean operations by enabling cinematic flming at great depth. Beginning in 1991, several action and documentary flms were produced using MIR recordings, including James Cameron's "Titanic" and the BBC's "Blue Planet." Each flm project led to the implementation of new technology, which could be used for scientifc research and observation of wrecks. For instance, in 1991, an IMAX camera was positioned inside the MIR's main sphere for deep-ocean flming. In 1995, James Cameron used a flm camera in a pressure cyl- inder outside of the MIR. In 1999, a high-defnition 3D camera was used for flming, positioned outside of MIR. In 1999, ROV modules on fber-optic wire were installed on the MIRs, which were able to fy 1 mile away from the vessels to explore inside such wrecks as the Titanic and the sunken German battleship Bismarck. These modules were used during the shooting of "Ghosts of the Abyss," "Expedition: Bismarck" and "Aliens of the Deep." Live Broadcast from the Titanic. The frst-ever TV broadcast from the deep ocean occurred in July 2005 with James Cameron using the MIRs, equipped with three ROV modules, to explore the inside of the Titanic wreck. TV signals were transmitted from MIR-2 at 3,800 meters depth through fber-optic line and received on board the RV Akademik Mstislav Keldysh then transmitted to land via satellite. During the two-hour broadcast, more than half a billion people watched. It was covered in Sea Technology magazine that year. Under-Ice Dives in the North Pole. August 2007 brought another world-history moment when footage of the geographical North Pole was provided for the frst time at 4,300 meters below the ice cover. For dive safety, the MIR group developed a hydroacoustical navigation system and improved the submersibles' propulsion, hydraulic and ballast systems. The dive was successful, and the crew of MIR-1 took samples of sediments and animals. Each MIR spent more than nine hours on the ocean bottom. It was the frst man-under-ice deep dive, which opened the way for future research of the geographical North Pole by manned submersibles.

The L-3 Klein UUV-3500 was developed as a side scan sonar with the unprecedented benefit of an advanced bathymetry payload for the growing Autonomous Underwater Vehicle (AUV), Remotely Operated Underwater Vehicle (ROV) and UUV markets. The UUV-3500 payload utilizes L-3 Klein's proprietary wideband technology for unmatched range and resolution, while operating at reduced power to deliver superior capability at a highly affordable price.
