Gävle thiab Sundsvall - Swedish choj corvettes
Modernized corvette HMS Gävle thaum lub sij hawm ib qho ntawm cov kev sim ya tawm ntawm Karlskrona. Thaum xub thawj siab ib muag, cov kev hloov tsis yog revolutionary, tab sis nyob rau hauv kev xyaum lub nkoj tau undergone tseem ceeb modernization.
Thaum Lub Tsib Hlis 4, Swedish Defense Materials Authority (FMV, Försvarets materielverk) tau xa cov hloov kho corvette HMS (Hans Majestäts Skepp) Gävle rau Marinen thaum lub sijhawm ua koob tsheej hauv Musco. Qhov no yog yuav luag 32-xyoo-laus lub nkoj, kev hloov kho tshiab uas yuav, ntawm lwm yam, kho lub qhov tom qab kev tshem tawm ib ntus ntawm Visby corvettes tshiab, uas tseem yuav dhau los ua kev hloov kho tshiab (ntau dua hauv WiT 2 / 2021) . Tab sis tsis yog xwb. Nws kuj yog ib qho cim ntawm cov teeb meem khoom siv cuam tshuam rau tub rog ntawm lub Nceeg Vaj ntawm Sweden, lossis, ntau dua - Försvarsmakten - cov tub rog ntawm lub tebchaws no. Lub xyoo ntawm kev zam rau pacifist thoob ntiaj teb kev nom kev tswv dhau los nrog kev ua phem ntawm Lavxias Federation tawm tsam Ukraine hauv 2014. Txij thaum ntawd los, muaj kev sib tw tawm tsam lub sijhawm los ntxiv dag zog rau Sweden kev tiv thaiv. Cov xwm txheej tam sim no dhau ntawm peb ciam teb sab hnub tuaj tsuas yog lees paub qhov kev txiav txim siab ntawm cov neeg los ntawm Stockholm txog qhov tseeb ntawm txoj kev xaiv.
HMS Sundsvall yog ib tug ntxaib corvette xaiv rau HTM (Halvtidsmodifiering) kev hloov kho ib ntus. Kev ua haujlwm ntawm nws kuj tseem xav kom ua tiav xyoo no, tom qab ntawd nws yuav rov qab mus rau qhov kev sib tw. Nws yuav tsum raug lees paub tias hu rau kev hloov kho tshiab ntawm cov txheej txheem ntawm lub hnub nyoog nruab nrab ntawm ib chav tsev nrog peb lub xyoos ntawm kev pabcuam tom qab lawv yog ib qho exaggeration txawm los ntawm Polish cov qauv. Ib lo lus zoo dua yuav yog "lub neej txuas ntxiv". Txawm li cas los xij peb hu nws, qhov kev rov qab los ntawm cov nkoj qub, muaj npe nrov hauv tebchaws Poland, tau tshwm sim rau lwm cov tub rog nyob sab Europe thiab. Qhov no yog qhov cuam tshuam ntawm kev tiv thaiv kev siv nyiaj txiag khov tom qab kawg ntawm Kev Tsov Rog Txias thiab cov lus teb tsis txaus siab rau cov kev hem thawj tshiab, suav nrog los ntawm Lavxias Federation.
Kev hloov kho Gävle thiab Sundsvall corvettes yuav siv feem ntau hauv kev ua haujlwm hauv tsev thoob plaws tag nrho cov kev tsis sib haum xeeb (kev sib haum xeeb-kev kub ntxhov-kev ua tsov ua rog). Lawv feem ntau yuav ua raws li kev soj ntsuam hauv hiav txwv, kev tiv thaiv (kev tiv thaiv kev tsim vaj tse, kev tiv thaiv kev tsis sib haum xeeb, kev txo qis thiab kev tiv thaiv), kev tiv thaiv ntug hiav txwv thiab kev ua haujlwm ntawm kev txawj ntse.
Baltic avant-garde ntawm lub 90s
Thaum Lub Kaum Ob Hlis 1985, FMV tau xaj plaub lub corvettes ntawm txoj haujlwm tshiab KKV 90 los ntawm Karlskronavarvet AB (hnub no Saab Kockums) hauv Karlskrona. Cov no yog: HMS Göteborg (K21), HMS Gävle (K22), HMS Kalmar (K23) thiab HMS Sundsvall (K24) uas tau xa mus rau tus neeg tau txais kev pab hauv xyoo 1990-1993.
Cov chav kawm Gothenburg yog qhov txuas ntxiv ntawm ib qho ua ntej ntawm ob qho me me Stockholm-chav kawm corvettes. Ib qho tshwj xeeb tshiab ntawm lawv qhov kev sib ntaus sib tua yog lub tshuab tiv thaiv huab cua tsis siv neeg, uas muaj peev xwm ntes tau, ntsuas qhov xwm txheej, thiab tom qab ntawd siv cov khoom siv (phom thiab virtual launchers) tawm tsam huab cua hem. Lwm qhov kev tsim kho tshiab yog kev siv cov dav hlau dej es tsis txhob siv cov kiv cua, uas, ntawm lwm yam, txo tus nqi ntawm cov npe hauv qab dej acoustic. Tus qauv tsim tshiab qhia txog kev sib koom ua ke ntawm kev sib ntaus sib tua thiab kev tswj hluav taws, nrog rau kev ua tiav cov qauv ntawm lub nkoj muaj ntau lub hom phiaj. Lub luag haujlwm tseem ceeb ntawm Gothenburg corvettes yog: sib ntaus sib tua lub hom phiaj, tso cov mines, sib ntaus sib tua submarines, escort, soj ntsuam thiab tshawb nrhiav thiab cawm cov haujlwm. Zoo li cov chav kawm Stockholm ua ntej, lawv tau raug cais raws li ntug dej hiav txwv corvettes (bushcorvettes) thiab txij li xyoo 1998 ua corvettes.
Gothenburg tau ua tub rog nrog 57mm L / 70 Bofors (hnub no BAE Systems Bofors AB) APJ (Allmålspjäs, Universal System) Mk2 autocannons thiab 40mm L / 70 APJ Mk2 (export brand SAK-600 Trinity) ob leeg nrog lawv tus kheej hluav taws kub tswj systems Celsius (CEROS CEROS) Lub vev xaib ntawm Celsiustech radars thiab optocouplers). Plaub ib leeg detachable 400 mm Saab Dynamics Tp42 / Tp431 torpedo hlab tau muaj rau kev tiv thaiv submarine kev ua tsov ua rog thiab tau muab tso rau ntawm lub hnub qub kom lawv cov firing tsis cuam tshuam nrog kev thauj mus los ntawm Thomson Sintra TSM 2643 Salmon hloov pauv qhov tob sonar, uas tau teeb tsa. tom qab ntawm qhov chaw nres nkoj. Tsis tas li ntawd, lawv tau muab faib ua khub rau hauv hneev thiab stern, kom lawv tuaj yeem tso ob lub torpedo tib lub sijhawm, tsis muaj kev ntshai ntawm kev sib tsoo. Lub ZOP tseem tau ua tub rog nrog plaub Saab Antiubåts-granatkastarsystemen 83 sib sib zog nqus grenade launchers (export hom: Elma ASW-600). Lwm cov cuab yeej siv riam phom, tab sis twb tau teeb tsa los ua lwm txoj hauv kev, yog Saab RBS-15 MkII coj cov tub rog foob pob hluav taws (txog yim) lossis plaub lub Saab Tp533 613 mm hnyav torpedo launchers. Kab ntsig tuaj yeem ntsia tau rau ntawm lub lawj sab saud, uas koj tuaj yeem tso dej hiav txwv mines thiab tso cov foob pob hluav taws xob. Tag nrho cov no tau ntxiv los ntawm ob lub Philips Elektronikindustrier AB (PEAB) Philax 106 foob pob hluav taws thiab dipole launchers thiab caj npab me. Raws li cov chaw tsim khoom, muaj 12 kev hloov kho ntawm corvette lub armament. Cov cuab yeej siv riam phom thiab cov khoom siv hluav taws xob cuam tshuam uas tsim los ntawm kev sib ntaus sib tua tau tswj hwm los ntawm kev sib koom ua ke ntawm CelsiusTech SESYM system (Strids-och EldledningsSystem rau Ytattack thiab Marinen, Sib ntaus sib tua thiab tswj hluav taws rau lub nkoj sib ntaus sib tua). Hnub no CelsiusTech thiab PEAB yog ib feem ntawm Saab Corporation.
Gothenburg tom qab nkag mus rau qhov kev pabcuam. Daim duab qhia txog qhov tseem ceeb ntawm cov nkoj thiab cov qauv hauv ntiaj teb camouflage rau lub sijhawm ntawd, nws thiaj li hloov los ntawm ntxoov grey.
Gothenburg yog lub nkoj kawg ua los ntawm cov hlau ntawm Karlskronavarvete/Kokums. Lub hulls yog ua los ntawm high yield zog steel SIS 142174-01, thaum lub superstructures thiab after hull overhang yog ua los ntawm txhuas alloys SIS144120-05. Lub mast, nrog rau kev zam ntawm lub hauv paus, yog ntawm cov yas (polyester-iav laminate) kev tsim kho, thiab nws yog cov cuab yeej no uas tau txais los ntawm Swedish tom ntej nto nkoj rau kev tsim ntawm lawv cov hulls.
Tus tsav tau muab los ntawm peb lub MTU 16V396 TB94 diesel xyaw nrog lub zog tas li ntawm 2130 kW / 2770 hp. (2560 kW / 3480 hp luv-term) mounted movably. Peb KaMeWa 80-S62 / 6 lub dav hlau dej (AB Karlstads Mekaniska Werkstad, tam sim no Kongsberg Maritime Sweden AB) tau ua haujlwm los ntawm gearboxes (tseem ntsia ntawm kev co-damping bases). Qhov kev daws teeb meem no tau muab ntau qhov zoo, suav nrog: txhim kho maneuverability, tshem tawm cov phaj rudders, tsis tshua muaj kev pheej hmoo ntawm kev puas tsuaj, lossis txo lub suab nrov uas tau hais los saum toj no (10 dB piv rau cov tshuab hloov tau). Dav hlau propulsion kuj tau siv rau lwm yam Swedish corvettes - xws li Visby.
