Pa­trolling with Sub­marines, Ships & Boats

Sur­face mar­itime pa­trol is an ac­tive pa­trolling of the area with sub­marines, ships and boats. Dur­ing war­time, mar­itime pa­trolling is crit­i­cal but it is also es­sen­tial in peace­time due to piracy, ter­ror­ism, smug­gling, pro­tec­tion of fish­ing ar­eas, ex­clu­sive

Dur­ing war­time, mar­itime pa­trolling is crit­i­cal but it is also es­sen­tial in peace­time due to piracy, ter­ror­ism, smug­gling, pro­tec­tion of fish­ing ar­eas, ex­clu­sive eco­nomic zone and sea lines of com­mu­ni­ca­tion.

mAR­ITIme PA­TROllING IS CAR­RIeD out by the navy, coast guard and law en­force­ment agen­cies for mon­i­tor­ing an area of wa­ter for any il­le­gal ac­tiv­ity. It can also be for other pur­poses like in­spec­tion and re­con­nais­sance but mainly it is car­ried out for se­cu­rity rea­sons. Sur­face mar­itime pa­trol is an ac­tive pa­trolling of the area with sub­marines, ships and boats. Dur­ing war­time, mar­itime pa­trolling is crit­i­cal but it is also es­sen­tial in peace­time due to piracy, ter­ror­ism, smug­gling, pro­tec­tion of fish­ing ar­eas, ex­clu­sive eco­nomic zone (eeZ) and sea lines of com­mu­ni­ca­tion (SlOC). Search and res­cue could also be car­ried out dur­ing pa­trolling due to the prox­im­ity of the pa­trolling el­e­ments. De­tec­tion of ac­tiv­ity can be car­ried out by hu­man be­ings but now elec­tronic sen­sors are be­ing used ex­ten­sively. Sur­face mar­itime pa­trolling is aug­mented by aerial plat­forms and sur­face sen­sors. Some ex­am­ples of aerial plat­forms are lock­heed mart­inÕs P-3 Orion anti-sub­ma­rine and mar­itime sur­veil­lance air­craft and Boe­ingÕs P-8 Po­sei­don multi-mis­sion mar­itime air­craft. He­li­copters, un­manned aerial ve­hi­cles (uAVs) and satel­lites are also widely used. Sur­face sen­sors are radars and aerostats mounted sen­sors. The type of sur­face mar­itime ca­pa­bil­ity will de­pend on a coun­tryÕs need. for ex­am­ple In­dia has a vast coast­line; it has state ma­rine po­lice (up to 12 nau­ti­cal miles (nm)/about 22 km), In­dian Coast Guard (be­tween 12 and 200 nm/about 22 km and 370 km) and the Navy op­er­at­ing be­yond 200 nm. Oth­ers will have a com­bi­na­tion of forces and equip­ment as per their se­cu­rity needs.

Sur­face Mar­itime El­e­ments

They come in all shapes and sizes. A few ex­am­ples are:

IAIÕs Ramta Di­vi­sionÕs Su­per Dvora class of mul­ti­mis­sion pa­trol and at­tack boats can carry out a va­ri­ety of mis­sions of off­shore pa­trol, eeZ con­trol, law en­force­ment, naval in­tel­li­gence, com­mand and con­trol, in­ter­dic­tion and board­ing of sus­pect tar­gets, as well as non­mil­i­tary mis­sions such as search and res­cue, hu­man­i­tar­ian as­sis­tance and dis­as­ter relief. All Su­per Dvora class vari­ants are fast and ag­ile, and de­signed to at­tain and sus­tain high op­er­at­ing tem­pos. The mini Dvora places em­pha­sis on high ma­noeuyuDelOlWy DQG RSHuDWlRQDO SuR­fi­flHQfy ZKlOH op­er­at­ing from the shal­low­est in­lets and beaches to shal­low lit­torals and be­yond. The lat­est gen­er­a­tion of Su­per Dvora mark (mk) I, II and III boats are deep sea ca­pa­ble eXW VSHflfifDOOy GHVlJQHG IRu D IXOO DuuDy RI lit­toral, anti-ter­ror, law en­force­ment and coastal se­cu­rity mis­sions. Su­per Dvora mk III is the lat­est fast pa­trol boat which is 25 me­tres long, has an op­er­a­tional ra­dius of 700 nm (about 1,296 km) while has speed in ex­cess of 45 knots (about 83 kmph) at a full dis­place­ment of 65 tonnes. In its at­tack mode, Ramta is cur­rently work­ing on a QXPeHu RI QHZ fRQ­fiJXuDWlRQV IRu WKH flHx­i­ble Su­per Dvora plat­form, among them the ÒStrikeÓ, or what Ramta refers to as the Òlit­toral war­riorÓ, equipped with a va­ri­ety of very ad­vanced pre­ci­sion weapon sys­tems. In ad­di­tion to the Is­rael Navy, the Su­per Dvora has been sold to nearly a dozen other in­ter­na­tional cus­tomers.

Ares class of boats are man­u­fac­tured by GRuP AReS Ship­yard, Spain. Ares 1200 ver­sion has a length of 11.95 m, max­i­mum speed of 40 knots (about 74 kmph) and a range of 400 nm (about 740 kmph). It car­ries one au­to­matic gyro sta­bilised ma­chine gun (12.7mm) and two man­ual ma­chine gun (12.7mm). Other weapon com­bi­na­tions are pos­si­ble on re­quest. The other ver­sions with tai­lor­made ca­pa­bil­i­ties are AReSA 1200 Defcon Rib, AReSA 1200 Stealth Rib, AReSA 750 com­man­dos rib, AReSA 550 com­man­dos rib and AReSA 400 com­man­dos rib.

larsen and Toubro (l&T) ma­rine and Ship De­sign Di­vi­sion has de­signed this craft which is 30 me­tres long with 90 tonnes dis­place­ment and can achieve a max­i­mum speed of 45 knots ( about 83 kmph). The in­ter­cep­tor boats has full alu­minium-al­loy hull for re­duced weight and is pow­ered by twin wa­ter-jet propul­sion sys­tems to en­able quick re­sponse. They are meant for the In­dian Coast Guard to carry out the role of coastal sur­veil­lance, search and res­cue, anti-smug­gling and anti-poach­ing opera- tions in close coast and can also op­er­ate ef­fec­tively in shal­low wa­ter. About 54 such boats have been or­dered.

Th­ese are a se­ries of 13, 26 me­tres high-speed in­ter­cep­tor boats de­signed and sup­plied in knocked down kits by Hen­der­son based Global ma­rine De­sign and as­sem­bled by ABG Ship­yard, Su­rat, for the In­dian Coast Guard. They are wide alu­minium hulled wa­ter jet pro­pelled ves­sels for op­er­a­tions in close coastal and shal­low waters. They have an en­durance of 500nm (about 926 km) at 25 knots (46 kmph) and ca­pa­ble of do­ing high speed up WR 45 NQRWV (DeRXW 83 NPSK) DQG DuH fiWWHG with a 12.7mm ÔPra­har­iÕheavy ma­chine gun.

Th­ese are a se­ries of 20 pa­trol boats de­signed by SeDS, Kochi, and be­ing built by Cochin Ship­yard lim­ited for the In­dian Coast Guard. The ship has been de­signed by SeDS, Kochi. The ves­sels have a length of 50 me­tres, de­signed speed of 33 knots (about 61 kmph). It has wa­ter jet propul­sion through triple Roll­sRoyce Kamewa 71S3np wa­ter jets. The ves­sel is ca­pa­ble of op­er­at­ing in shal­low waters and of­fer higher speeds and bet­ter ma­noeu­vra­bil­ity than con­ven­tional pro­pel­lers. The nav­i­ga­tion pack­age is be­ing sup­plied by Northrop Grum­manÕs Sperry ma­rine busi­ness unit. The pri­mary role of the ves­sel lQfOXGH fiVKHulHV SuRWHfWlRQ DQG PRQlWRu­ing, pa­trol within ex­clu­sive eco­nomic zone, coastal pa­trol, anti-smug­gling, anti-piracy, and search and res­cue op­er­a­tions.

fif- teen such boats are be­ing built by Bharati Ship­yard for the In­dian Coast Guard. The ves­sels have a length of 28 me­tres with a speed of more than 35 knots (about 64 kmph). The ves­sels can per­form high­speed in­ter­cep­tion, close-coast pa­trol, low­in­ten­sity mar­itime op­er­a­tions, search and res­cue and sur­veil­lance.

This class of pa­trol craft are larger in size. The In­dian Coast Guard has or­dered eight IPVs which are be­ing de­signed and built by the Gar­den Reach Ship­builders and engi­neers lim­ited, out of which the sev­enth has been com­mis­sioned dur­ing Au­gust 10. The IPV can achieve a max­i­mum speed of 31.5 knots (about 58 kmph) and at a speed of 14 knots (about 26 kmph), it has an en­durance of 1,500 nm (about 2,778 km). The spe­cial fea­tures of the ship in­clude an in­te­grated bridge sys­tem, in­te­grated ma­chin­ery con­trol sys­tem and an in­dige­nously built 30PP JXQ-PRXQW ZlWK fiuH fRQWuRO VyVWHP.

They are large, off­shore pa­trol craft in ac­tive ser­vice with the In­dian Navy. Three lead ships were built by Korea Ta­coma, now part of Han­jin Group. The Sukanya class have large hulls, al­though they are lightly armed since they are utilised pri­mar­ily for off­shore pa­trol of In­di­aÕs ex­clu­sive eco­nomic zone. How­ever, they are ca­pa­ble of be­ing heav­ily armed and up­graded to light frigates if the need arise. It has a dis­place­ment of 1,890 tonnes when fully loaded, length of 101 me­tres, speed of 21 knots
