Freya or UC1 Freya (in Danish: Freja) was the first private Danish submarine, and thus first amateur electric sub in Denmark. It was built by Peter Madsen and Claus Nørregaard {{cite web |url= http://politiken.dk/oekonomi/art4903083/G%C3%B8r-det-selv-ub%C3%A5d-nummer-to |title= Gør det selv-ubåd nummer to |date= 21 February 2004 |author= Martine Lind Pedersen |publisher= Politiken.dk |language=da}} in 2001–2002, as a demonstrator to try submarine technology. Having made over 500 dives, it was decommissioned, as it was not designed for a long service life. It was decommissioned in 2006 after UC2 Kraka had been worked up. The submarine was then docked and allowed to decay. Final decontamination was done, and it was towed out to sea by UC3 Nautilus, in August 2008, and sunk as an artificial reef near Copenhagen.{{Cite web |url= http://www.uc3nautilus.dk/ |title=UC3 Nautilus Homepage, FAQ |work=uc3nautilus.dk |access-date=21 December 2012 |archive-url= https://web.archive.org/web/20100307042901/http://www.uc3nautilus.dk/faq.htm |archive-date=7 March 2010| url-status=dead }} Peter Madsen, email notice, [http://www.psubs.org/mlist/archive/0808/msg00057.html "[PSUBS-MAILIST] UC3 Nautilus at sea with UC1 Freya..."], 10 Aug 2008 {{cite episode |series= Go Deep |title= Subshop |number= 15 |season= 1 |airdate= 16 April 2009 }} {{cite news |url= http://www.abc.net.au/news/2017-08-14/peter-madsen-engineer-submarine-builder-manslaughter-charge/8803156 |title= Peter Madsen: Did a Danish entrepreneur sink his homemade submarine with a journalist aboard? |author= Jonathan Hepburn |date= 22 August 2017 |publisher= Australian Broadcasting Corporation }}
Freya is named after the Norse goddess of fertility and love. {{cite web |url= https://ing.dk/artikel/ubad-med-hjerter-63715 |title= Ubåd med to hjerter |author= Tharrsica Kankesan |date= 1 May 2005 |publisher= Ingeniøren |language=da}}
Construction
The sub was built at Peter Madsen's workshop in Farum, Denmark. {{cite web |url= https://ing.dk/artikel/selvbyggerubad-skal-sejle-verden-rundt-63716 |title= Selvbyggerubåd skal sejle verden rundt |author= Tharrsica Kankesan |date= 1 May 2005 |publisher= Ingeniøren |language=da}} Freya was completed in 2002. It was built with only an electric drive, a 3.1-kW Sauer-Danfoss 24V DC electric motor. Coupled with a 24V 200Ah Setronic-Flamm GS gel battery, this gave a range of {{cvt|6|mi|km|order=flip}}, but a charging time of 24 hours. This gave a cruise radius of {{cvt|3|mi|km|order=flip}}. The electric motor was sourced from a forklift. The sub had a service depth of {{cvt|15|m|ft}}, and a theoretical crush depth of {{cvt|135|m|ft}}. The sub was {{cvt|7.5|m|ftin}} long, {{cvt|1.0|m|ftin}} wide, and {{cvt|2.9|m|ftin}} tall from keel to top of periscope. It could reach {{convert|3.5|kn|kph mph}} on the surface or {{convert|2.5|kn|kph mph}} submerged. {{cite web |publisher= Ingeniøren |url= https://ing.dk/artikel/danmarks-forste-diesel-elektriske-amator-ubad-63702 |title= Danmarks første diesel-elektriske amatør-ubåd |author= Tharrsica Kankesan |date= 28 April 2005 |language=da}} Freya was not equipped with an air compressor, which limited the time length of dives. {{cite news |url= https://www.b.dk/danmark/ubaad-lokker-droemmere-til |title= Ubåd lokker drømmere til |agency= KL |publisher= Berlingske Tidende |date= 2 May 2005 |language=da}} The sub could hold 2 people. As UC1 was a prototype, it was built out of regular steel, for enhanced strength, over aluminum or fibreglass, and making it cheaper than stainless steel. Operating costs originally were about 6 DKK worth of electricity for a couple of hours cruising.
History
Freya was completed in 2002, and she was put to sea, starting voyages.
In July 2002, out of the water for inspection and refit, it was crushed by a transport accident, when the truck it was on passed under a low bridge, and the attached crane was knocked over, crushing the conning tower and central portion. Insurance monies paid by the transport company were used to pay for repairs, making it seaworthy again, later in 2002. The repairs were done by Madsen and company. {{cite web |url= https://ing.dk/artikel/ubaden-freja-sejler-igen-44356 |title= Ubåden Freja sejler igen |author= Signe Lund |date= 1 October 2002 |publisher= Ingeniøren |language=da}}
After decommissioning, it was sunk to the bottom of the Øresund. {{cite news |url= http://forte.delfi.ee/news/tehnika/mida-me-skandaalsest-peter-madsenist-ja-tema-katsetest-rakettide-ja-allveelaevadega-tegelikult-teame?id=79202444 |title= Mida me skandaalsest Peter Madsenist ja tema katsetest rakettide ja allveelaevadega tegelikult teame |date= 16 August 2017 |author= Heiki Suurkask |language= et |publisher= Forte }}
