The ship was launched on 17 December 1912 [3] and was initially christened Polaris after the North Star. [4] She was 144 ft (44 m) long, with a 25 ft (7.6 m) beam, [5] and measured 350 tons gross. [6] Her original purpose was to provide luxurious accommodation for small tourist and hunting parties in the Arctic as an ice-capable steam yacht. [7]
USCGC Southwind (WAGB-280) was a Wind-class icebreaker that served in the United States Coast Guard as USCGC Southwind (WAG-280), the Soviet Navy as the Admiral Makarov, the United States Navy as USS Atka (AGB-3) and again in the U.S. Coast Guard as USCGC Southwind (WAGB-280).
The V-280 is designed for a cruising speed of 280 knots (320 mph; 520 km/h), hence the name V-280. It has a top speed of 300 knots (345 mph; 556 km/h), a range of 2,100 nautical miles (2,400 mi; 3,900 km), and an effective combat range of 500 to 800 nmi (580 to 920 mi; 930 to 1,480 km).
The German Type XXI U-boat, with a large battery capacity, streamlining to maximize underwater speed, and a snorkel, was the submarine of the immediate future. The Greater Underwater Propulsion Power Program (GUPPY) conversion program was developed to give some Balao - and Tench -class submarines similar capabilities to the Type XXI.
The Cirrus SR Sport, simply called the Cirrus SRS, was a version of the B&F Fk14 Polaris that was intended to be marketed as a light-sport aircraft by U.S.-based aircraft manufacturer Cirrus Design (now called Cirrus Aircraft), and was promoted from 2007 until its suspension in 2009 during the economic crisis.
An engineer [19] at the Cornell Aeronautical Laboratory (CAL) used computer modeling to calculate the stunt and specified 1,460.06 kilograms (3,219 lb) for the weight of car and driver, the exact angles and the 15.86-metre (52 ft) distance between the ramps, as well as the 64.36-kilometre-per-hour (40 mph) launch speed.

The second mission in the Polaris Program will launch via a Falcon 9 Block 5 vehicle with a Crew Dragon capsule. SpaceX and Polaris had studied a crewed mission to lift the Hubble Space Telescope into a higher orbit to prevent it from burning up in the atmosphere, [4] [5] but this option was rejected by NASA in June 2024.

In Windows NT, the booting process is initiated by NTLDR in versions before Vista and the Windows Boot Manager (BOOTMGR) in Vista and later. [4] The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory.
