〃You　want　our　helo　to　back　you　up？〃
〃Roger　that；　yes；　but　tell　him　to　keep　low。〃
Seconds　later　the　frigate's　SH…2F　Sea　Sprite　helicopter　sped　off　north；　her　magnetic　anomaly　detector　trailing　out　by　cable　from　a　shroud　on　the　right　side　of　the　aircraft。　Essentially　a　highly　sensitive　magnetometer；　it　could　detect　the　disturbance　in　the　earth's　magnetic　field　made　by　a　large　chunk　of　ferrous　metal…like　the　steel　hull　of　a　submarine。
〃Signal　on　number　six　is　now　medium…strength。　Signal　on　seven　remains　medium。〃　The　plotting　team　took　this　to　mean　that　the　submarine　was　heading　south。
〃I　can　give　you　a　working　range　figure；〃　ASW　said　to　the　TAO。　Forty…two　to　forty…five　thousand　yards；　bearing　three…four…zero　to　three…three…six。〃　The　frigate　relayed　this　at　once　to　the　Orion。
As　they　watched　on　radar；　the　P…3C　quartered　the　area；　flying　very　precise　tracks　across　the　box　of　ocean　defined　by　Pharris's　sonar　data　as　the　probable　location　of　the　submarine。　A　puter　system　plotted　the　lines　as　they　extended　to　the　south。
〃Pharris；　this　is　Bluebird。　Our　data　indicates　no　friendly　subs　in　the　area。　Please　confirm；　over。〃
〃Roger　that；　Bluebird。　We　confirm　no　reports　of　friendlies　in　the　area。〃　Morris　had　checked　that　himself　half　an　hour　before。
〃Signal　strength　increasing　on　number　six。　We　now　have　a　weak　signal　on　number　five。　Number　seven　is　fading　out。〃　The　technician　was　really　struggling　to　be　professionally　impassive　now。
〃Range　is　firming　up。　Estimate　target　speed　roughly　eight　knots；　distance　forty…three　thousand　yards。〃
〃Transient！　Transient！〃　called　the　ship　sonar　operator。　A　metallic　noise　had　e　from　the　target　bearing。　A　closing　hatch；　a　dropped　tool；　an　opening　torpedo　tube　door…something　had　made　a　uniquely　man…made　sound。
〃Confirm　mechanical　transient；　copied　on　buoys　five　and　six；〃　the　aircraft　called　immediately。
〃Confirmed；〃　Pharris's　TAO　answered。　〃We　got　that　on　the　towed　array；　too。　We　evaluate　the　contact　as　positive　submarine　at　this　time。〃
〃Concur；〃　the　Orion　replied。　〃Positive　Redboat　classification…madman！　Madman；　madman；　smoke　away！　We　have　a　NLAD　contact。〃　A　big　spike　appeared　on　the　MAD　readout。　Instantly；　a　crewman　flipped　a　switch　to　deploy　a　smoke　marker　and　the　aircraft　turned　hard　right　to　circle　back　on　the　contact　point。
〃Plotted！〃　The　tactical　action　officer　marked　the　position　on　his　tactical　display　scope　with　a　large　V　symbol。
The　helo　raced　in　on　the　contact　as　the　Orion　circled　back。
〃Madman！〃　its　systems　operator　called　out；　and　the　helo　dropped　its　own　smoke　bomb；　slightly　south　and　west　of　the　Orion's。
The　data　was　now　being　relayed　to　the　frigate's　torpedo…tube　and　ASROC　attack　directors。　Neither　had　anything　like　the　range　to　engage　the　target；　but　that　could　change　quickly。
〃Patience；〃　Morris　breathed　from　his　chair　in　the　CIC；　then　louder：　〃Take　your　time；　people。　Let's　lock　this　guy　in　before　we　fire。〃
The　Orion's　tactical　coordinator　agreed；　forcing　himself　to　relax　and　take　the　time　needed。　The　P…3　and　the　helicopter　made　another　MAD　run　north　to　south。　This　time　the　Orion　got　a　reading　and　the　helo　did　not。　Another　run；　and　both　had　the　contact's　course　line。　Next　came　an　east…to…west　run。　At　first；　both　missed；　but　on　the　second　run　both　had　him。　The　contact　was　no　longer　an　it。　Now　it　was　a　he；　a　submarine　being　driven　by　a　man。　Control　of　the　operation　now　passed　exclusively　to　the　tactical　coordinator　on　the　Orion。　The　big　patrol　aircraft　orbited　two　miles　away　as　the　helicopter　lined　up　for　the　final　pass。　The　pilot　made　a　very　careful　check　of　his　tactical　display；　then　locked　his　eyes　on　the　gyropass。
The　helo　began　the　last　MAD　run；　with　the　Orion　two　miles　behind　it。
〃Madman；　madman；　smoke　away！〃　The　final　smoke　marker　dropped；　a　green　flare　floating　on　the　surface。　The　Sea　Sprite　banked　hard　to　the　right　to　clear　the　area　as　the　Orion　came　in　low。　The　pilot　watched　the　smoke's　movement　to　figure　wind　drift　as　he　lined　up　on　the　target。　The　P…3C's　bomb　bay　doors　opened。　A　single　Mk…46　ASW　torpedo　was　armed　for　launch。
〃Torp　away！〃
The　torpedo　dropped　cleanly；　its　braking　parachute　trailed　out　of　the　tail　to　make　sure　the　weapon　entered　the　water　nose　down。　The　Orion　also　dropped　an　additional　sonobuoy；　this　time　a　directional　DIFAR。
〃Strong　signal；　bearing　one…seven…niner。〃
The　torpedo　dove　to　two　hundred　feet　before　beginning　its　circular　search。　Its　high…frequency　sonar　came　on　as　it　reached　search　depth。　Things　started　happening　quickly。
The　submarine　had　been　oblivious　to　the　activity　over　her　head。　She　was　an　old　Foxtrot。　Too　old　and　too　noisy　for　front…line　operations；　she　was　there　nonetheless；　hoping　to　catch　up　with　the　convoy　reported　to　her　south。　Her　sonar　operator　had　noted　and　reported　a　possible　overhead　splash；　but　the　captain　was　busy　plotting　the　position　of　the　convoy　he　had　been　ordered　to　approach。　The　torpedo's　homing　sonar　changed　that。　Instantly；　the　Foxtrot　went　to　flank　speed；　turning　hard　to　the　left　in　a　pre…planned　evasion　maneuver。　The　suddenly　increased　noise　of　her　cavitating　screws　was　discernible　to　several　sonobuoys　and　Pharris's　tactical　sonar。
The　torpedo　was　in　ping…and…listen　mode；　using　both　active　and　passive　sonar　to　find　its　target。　As　it　pleted　its　first　circle；　the　passive　receptors　in　the　nose　heard　the　cavitation　noises　of　the　submarine　and　homed　in　on　them。　Soon　the　active　sonar　pings　were　reflecting　off　the　submarine's　stem　as　it　dodged　left　and　right　trying　to　get　away。　The　torpedo　automatically　went　to　continuous　pinging；　increasing　to　maximum　speed　as　it　homed　in　on　its　target　like　the　remorseless　robot　it　was。
The　sonar　operators　on　the　aircraft　and　the　frigate　had　the　best　picture　of　what　was　happening。　As　they　watched；　the　bearing　lines　of　the　submarine　and　torpedo　began　to　converge。　At　fifteen　knots；　the　Foxtrot　was　too　slow　to　run　away　from　the　forty…knot　torpedo。　The　submarine　began　a　radical　series　of　turns　with　the　torpedo　in　pursuit。　The　Mk…46　missed　its　first　attempt　for　a　kill　by　twenty　feet；　and　immediately　turned　for　another　try。　Then　the　submarine's　captain　made　a　mistake。　Instead　of　continuing　his　left　turn；　he　reversed　it；　hoping　to　confuse　the　oning　torpedo。　He　ran　directly　into　its　path　。　。　。
Immediately　overhead；　the　helicopter　crew　saw　the　water　appear　to　leap；　then　froth；　as　the　shock　wave　of　the　explosion　reached　the　surface。
〃We　have　warhead　detonation；〃　the　pilot　reported。　A　moment　later　his　systems　operator　dropped　a　passive　buoy。　The　sound　came　into　them　in　less　than　a　minute。
The　Foxtrot　was　dying。　They　heard　the　sounds　of　air　blowing　into　her　ballast　tanks　and　continued　flank　power　from　her　electric　motors；　her　propellers　struggling　to　overe　the　weight　of　water　entering　the　hull　and　drive　the　wounded　submarine　to　the　surface。　Suddenly　the　engine　sounds　stopped。　Two　minutes　later；　they　heard　the　metallic　scream　of　internal　bulkheads　being　torn　asunder　by　water　pressure　as　the　submarine　fell　below　crush　depth。
〃This　is　Bluebird。　We　score　that　one　as　a　kill。　Can　you　confirm；　over？〃
〃Roger；　Bluebird；〃　the　ASW　officer　answered。　〃We　copied　blowing　air　and　breakup　noises。　We　confirm　your　kill。〃　The　crewmen　cheered；　forgetting　the　decorum　that　went　with　duty　in　CIC。
〃All　right！　That's　one　less　to　worry　about。　We'll　give　you　a　big　assist　on　that　one；　Pharris。　Nice　job　from　your　sonar　folks　and　the　helo。　Out。〃　The　Orion　increased　power　and　returned　to　her　patrol　station　forward　of　the　convoy。
〃Assist；　hell！〃　snorted　the　ASW　officer。　〃That　was　our　contact。　We　could　have　dropped　the　torp　on　him　just　as　easy　as　he　did。〃　Morris　punched　him　in　the　shoulder　and　went　up　the　ladder　to　the　pilothouse。
The　bridge　crew　was　all　grins。　Soon　the　bosun's　mate　would　paint　half　of　a　red　submarine　silhouette　next　to　the　pilothouse　door。　It　had　not　struck　them　yet　that　they　had　just　helped　in　the　killing　of　a　hundred　young　men　not　at　all　unlike　themselves；　their　lives　cut　short　by　the　hammering　pressure　of　the　North　Atlantic。
〃What's　that？〃　called　a　lookout。　〃Possible　explosion　on　the　starboard　beam！〃
Morris　grabbed　his　binoculars　and　raced　out　the　open　door。　The　lookout　pointed。
A　column　of　black　smoke　was　reaching　into　the　sky　from　the　direction　of　the　convoy。　Someone　else　had　just　gotten　his　f
