The system monitors all bands, but must be set to analyze in only one at a time (frequency, PRF, pulse width). It is not clear whether this is the same system as the AR 700 system (see above).

Notes - Teardrop hull design.
- Two Chien Lung/Hai Lung class submarines, which are variations on the Zwaardvis (2) design,
   were exported to Taiwan in the 1980s.
- After the Dutch Navy decommissioned these subs there have been many rumours about a possible deal,  between R.D.M. and a foreign country, to sell these two submarines. Check the news section and the individual boat histories of Zwaardvis (2) and Tijgerhaai (2) for more information.
- Reserve fuel tank #5 normally used to store 25 t of water
