The four tenders resulting from the study were submitted during October and November 1986. Although the IKL/HDW design was rated highest during the initial inspection, the evaluation team found that the German proposal was less attractive than previously thought. Although IKL/HDW claimed that their boat could meet the RAN's performance requirements, the evaluators concluded from the information provided that doing so would require the deactivation of all non-essential and some essential systems. Conversely, Kockums' proposal conceded that they did not meet the requirements, although evaluators found that the figures failed by only narrow margins, and believed that these were conservative. The evaluation team recalculated the capability statistics for both submarines to a common baseline, portraying the predicted Australian operating conditions, which generally saw Kockums' figures revised upwards, and those from IKL/HDW downwards. This resulted in growing support for the Type 471 bid, and outcries from the IKL and HDW groups, who questioned the validity of the recalculations and if the Australian evaluators had the experience to do this correctly.
