Katoloso ea li-frigate tsa Mofuta oa 41 le Mofuta oa 61 tse hlahisitsoeng ka har'a Sea and Ships Special Issue 3/2016 e ne e le letoto la lihlopha tse ling tse peli tsa Royal Navy escort units, tse tsejoang e le Mefuta e ntlafalitsoeng ea 12 le 12, e nang le hydrodynamics e ntlafalitsoeng, propulsion le lisebelisoa.
Bakeng sa lithuto tse mabapi le morero oa Borithane oa li-block tsa PDO, tse entsoeng karolong ea bobeli ea lilemo tsa bo-40, sepheo sa "mohlala" e ne e le likepe tse tsamaeang ka tlas'a metsi tse khonang ho hlahisa lebelo la li-knots tse ka bang 18 sebakeng se kolobisitsoeng, ka mohopolo o le mong oa hore e ka eketseha haufinyane. Ka hona, Admiralty e ile ea batla hore hape li-frigates tse entsoeng li khone ho tsamaea ka lebelo le phahameng la li-knots tse 25 ka mochine oa motlakase oa lik'hilomithara tse 25 20 le sebaka sa lik'hilomithara tse 000 3000 tsa nautical ka lebelo la li-knots tse 15. Litlhoko tsena li ne li sebetsa feela ho fihlela qetellong ea 1947, qalong ea selemo se secha, ho ne ho e-na le liphetoho tse kholo tseleng ea Royal Navy ho bothata ba PDO. Ho ea ka litaelo tsa hae tsa morao-rao, likepe tse felehelitseng li ne li lokela ho fihla lebelo la 10 knots ka potlako ho feta likepe tse tsamaeang ka tlas'a metsi tsa lira. Ho tloha mona, ka mor'a liphuputso, ho ile ha fumanoa hore li-knots tse 27 li tla ba molemo ho "batsomi" ba bacha. ka lebelo le tšoanang la moruo. Ka potlako ho ile ha hlaka hore nts'etsopele ea tsamaiso ea turbine propulsion system eo ka lehlakoreng le leng e neng e le bobebe ebile e kopane, 'me ka lehlakoreng le leng e ka hlahisa matla a hlokahalang ho finyella li-watts tse 3000 ha ho ntse ho boloka tšebeliso ea mafura e lumellang 4500 mm ea maeto, e se be bonolo hakaalo. E le ho etsa hore litlhoko tsena e be tsa sebele, Admiralty e ile ea qetella e lumetse ho fokotsa lebelo la moruo ho li-knots tse 27 (e tlaase ka ho fetisisa e lumelletsoeng bakeng sa ho tsamaisa likoloi tse tsamaeang ka likhoto tse 4500).
Qalong, mosebetsi oa yuniti e ncha ea PDO o ile oa tsoela pele butle haholo, ka lebaka la bohlokoa bo phahameng bo fanoeng ho fetola bahlaseli ba Ntoa ea II ea Lefatše karolo ea frigate. Moralo oa moralo o ne o lokile ka Hlakola 1950. Mosebetsi oa li-frigates tse ncha ha oa ka oa qala ho fihlela qalong ea thibelo ea Berlin Bophirimela, e ileng ea etsahala bosiung ba la 23-24 June, 1948. Morerong oa bona, ho ile ha etsoa qeto ea ho sebelisa likarolo tse alimiloeng ho mofuta o hlalositsoeng pejana oa 41/61 frigates, ho kenyeletsoa. low superstructure, lithunya ka sebōpeho sa lithunya tse peli tsa Mk V bokahohleng ka 114 mm Mk VI turret (e laoloang ke tsamaiso ea ho laola mollo oa Mk 6M), hammoho le 2 Mk 10 Limbo seretse se kentsoeng ka "hantle". Thepa ea radar e ne e tla ba le mofuta oa 277Q le 293Q radar. Hamorao, mefuta e 'meli ea 262 (bakeng sa mollo o thibelang lifofane libakeng tse khutšoanyane) le mofuta oa 275 (bakeng sa mollo o thibelang lifofane libakeng tse telele) li ile tsa eketsoa ho tsona. Mefuta ea Sonar 162, 170 le 174 (hamorao e ile ea nkeloa sebaka ke mofuta o mocha oa 177) e ne e lokela ho kenyelletsoa thepa ea sonar. Hape ho ile ha etsoa qeto ea ho kenya libetsa tsa torpedo. Qalong, li ne li lokela ho kenyelletsa li-launcher tse 4 tse kentsoeng ka ho sa feleng tse nang le pokello ea li-torpedoes tse 12. Hamorao, litlhoko tsena li ile tsa fetoloa hore e be likamore tse 12, tseo tse 8 (4 ka boto e neng e lokela ho ba li-launcher tse emeng), 'me tse ling tse 4, tsamaisong ea 2xII, rotary.
Tšebeliso ea limela tse ncha tsa motlakase oa turbo-steam bakeng sa propulsion e bile le phello e mpe ho karohano ea boima le boholo. E le hore sekepe se khone ho se haha, se ile sa tlameha ho atolosoa, ka mor'a liphuputso tse ngata, bolelele ba sona bo ile ba eketseha ka 9,1 m le bophara ba 0,5 m. ts'ebetso e ntle haholo, ha tlhahlobo ea letamo la ho sesa e bontšitse hore ho lelefatsa ha sekepe ho ile ha ntlafatsa phallo ea metsi a laminar, ho eketsa lebelo le fihletsoeng ("nako e telele").
