Was watching SECONDS FROM DISASTER on SKY the other night, about how the KURSK was lost. At the end, there was a trailer for a new programme at 2100 next Friday (August 11th). In this, it seems that there are allegations it was sunk by a torpedo, not the internal explosion that has been more or less accepted as the cause of the sinking. Should be worth a look, but if I remember rightly, aren't the OSCAR's double hulled ? What sort of torpedo could inflict such massive damage and does such a non-nuclear fish exist ?
