<P> Executive producer Andy Harries gained hold of the novel and pitched a television adaption to Sky, even though he had not read it . Sky commissioned the series as part of a £ 10 million commitment to adapt novels into original dramas following the successes of adapting Terry Pratchett's Discworld novels . Following Cinemax's participation from the second series, the series faced a re-imagining due to the absence of first series lead Richard Armitage, who was at the time filming The Hobbit in New Zealand . Before filming several cast members participated in bootcamp training by former SAS and Special Boat Service (SBS) officers . The series was filmed on location in South Africa, although parts of the second series were filmed in Hungary . </P> <P> Ratings for Strike Back were relatively high for the original networks . The Sky1 premiere was viewed by almost 400,000 viewers (according to overnight figures), tripling the average audience share for the channel's time slot after three months . Project Dawn premiered to over 600,000 . The Cinemax premiere saw the network's best ratings since 2005 . The first five series have been or will be released on DVD and Blu - ray Disc . </P> <Table> <Tr> <Th_colspan="2"> Series </Th> <Th> Banner title </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr> <Tr> <Th> First aired </Th> <Th> Last aired </Th> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> Strike Back </Td> <Td_colspan="2"> 6 </Td> <Td_colspan="1"> 5 May 2010 (2010 - 05 - 05) (Sky One) 25 October 2013 (2013 - 10 - 25) (Cinemax) </Td> <Td> 19 May 2010 (2010 - 05 - 19) (Sky One) 29 November 2013 (2013 - 11 - 29) (Cinemax) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> Project Dawn </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 21 August 2011 (2011 - 08 - 21) (Sky One) 12 August 2011 (2011 - 08 - 12) (Cinemax) </Td> <Td> 23 October 2011 (2011 - 10 - 23) (Sky One) 21 October 2011 (2011 - 10 - 21) (Cinemax) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> Vengeance </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 2 September 2012 (2012 - 09 - 02) (Sky One) 17 August 2012 (2012 - 08 - 17) (Cinemax) </Td> <Td> 4 November 2012 (2012 - 11 - 04) (Sky One) 12 October 2012 (2012 - 10 - 12) (Cinemax) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> </Td> <Td> Shadow Warfare </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 28 October 2013 (2013 - 10 - 28) (Sky One) 9 August 2013 (2013 - 08 - 09) (Cinemax) </Td> <Td> 30 December 2013 (2013 - 12 - 30) (Sky One) 18 October 2013 (2013 - 10 - 18) (Cinemax) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 5 </Td> <Td> Legacy </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 3 June 2015 (2015 - 06 - 03) (Sky One) 31 July 2015 (2015 - 07 - 31) (Cinemax) </Td> <Td> 29 July 2015 (2015 - 07 - 29) (Sky One) 9 October 2015 (2015 - 10 - 09) (Cinemax) </Td> </Tr> <Tr> <Td> </Td> <Td_colspan="1"> 6 </Td> <Td> Retribution </Td> <Td_colspan="2"> 10 </Td> <Td_colspan="1"> 31 October 2017 (2017 - 10 - 31) (Sky One) 2 February 2018 (2018 - 02 - 02) (Cinemax) </Td> <Td> 28 February 2018 (2018 - 02 - 28) (Sky One) 6 April 2018 (2018 - 04 - 06) (Cinemax) </Td> </Tr> </Table> <Tr> <Th_colspan="2"> Series </Th> <Th> Banner title </Th> <Th_colspan="2"> Episodes </Th> <Th_colspan="2"> Originally aired </Th> </Tr>
