Com­bat Mod­ule for Ar­mored Ve­hi­cles Up­grade


HE LIGHT-WEIGHT CAT­E­GORY COM­BAT ve­hi­cles are able to de­ter­mine the com­bat po­ten­tial of a coun­try’s Armed Forces due to their ap­pli­ca­tion ver­sa­til­ity. In­fantry fight­ing ve­hi­cles (BMP-1, BMP-2, BMP-3) and air­borne as­sault ve­hi­cles (BMD-3, BMD-4) are the most com­mon hard­ware of land forces and air­borne troops.

Cur­rently a huge fleet of such com­bat ve­hi­cles is in ser­vice with the Rus­sian Army and abroad. These ve­hi­cles have been pro­duced for sev­eral decades and presently their weapon sys­tems do not meet mod­ern re­quire­ments. How­ever, their life cy­cle is quite long and reaches 30-40 years.

Many coun­tries keep on up­grad­ing the main fleet of their com­bat ve­hi­cles. In Rus­sia, a BMP-2 me­chan­i­cal mod­ule was se­lected as a ba­sis for designing a uni­form com­bat mod­ule weigh­ing be­low 3 tons for up­grad­ing Rus­sian com­bat ve­hi­cles. Rus­sian in­fantry fight­ing ve­hi­cle BMP-2, be­ing the main com­bat ve­hi­cle of mul­ti­ple coun­tries’ land forces, was adopted for ser­vice in 1980 and used to ex­ceed most of its for­eign coun­ter­parts in terms of com­bat ca­pa­bil­i­ties. Nowa­days BMP-2 still ba­si­cally meets the mod­ern re­quire­ments.

The anal­y­sis of cur­rent state and devel­op­ment ten­den­cies of weapons and fire con­trol sys­tems shows that BMP-2 weapon sys­tem is fall­ing be­hind the mod­ern level a num­ber of pa­ram­e­ters: guided weapon fire is pos­si­ble from sta­tion­ary po­si­tion only be­cause of wire com­mand link avail­abil­ity; Konkurs ATGM has low pen­e­tra­tion ca­pa­bil­ity and is not ef­fec­tive against mod­ern tanks; Konkurs ATGM has low fir­ing rate due to man­ual reload­ing of the launcher; at night the sys­tem may fire only au­to­matic can­non or PKT ma­chine-gun at range not ex­ceed­ing 800 m; the fire con­trol sys­tem is not au­to­mated and does not al­low for ac­cu­rate fir­ing, lim­it­ing the ef­fec­tive range of 30 mm can­non to 1100–1400 m. when fir­ing on the move the sys­tem does not pro­vide for re­quired ac­cu­racy of line of sight sta­bi­liza­tion due to BPK-2-42 sight rigidly bound to the weapon; 30 mm pro­jec­tiles flat tra­jec­tory fir­ing is not ef­fi­cient against prone or en­trenched man­power; fire at aerial targets car­ried out us­ing cen­ter rings of 1PZ-3 sight, ac­tu­ally de­liv­ers only a psy­cho­log­i­cal ef­fect. The fire­power of a com­bat ve­hi­cle is de­ter­mined by its weapon sys­tem, thus, the in­crease of com­bat ef­fi­ciency may be achieved by weapon sys­tem mod­ern­iza­tion. BMP-2 has a high weapon sys­tem up­grade po­ten­tial. The chal­lenge of in­creas­ing the fire­power of ex­ist­ing BMPs pro­vid­ing their su­pe­ri­or­ity over other mod­ern ve­hi­cles has been suc­cess­fully met by KBP In­stru­ment De­sign Bureau.

The up­grade was im­ple­mented on a se­ri­ally pro­duced BMP-2 tur­ret with 2A42 au­to­matic can­non (not chang­ing the me­chan­i­cal mod­ule and tur­ret in­ter­nal lay­out). The de­sign con­cept im­plies the fol­low­ing: mount of two Kor­net-E ATGM launch­ers on the tur­ret sides, each launcher equipped with in­de­pen­dent electro­mechan­i­cal ver­ti­cal drive and car­ry­ing two ready for fire mis­siles; re­place­ment of stan­dard BPK-2-42 sight with com­bined gunner’s sight equipped with in­de­pen­dent LOS sta­bi­liza­tion sys­tem and in­cor­po­rat­ing op­ti­cal, IR and laser range-find­ing chan­nels, as well as mis­sile guid­ance chan­nel; in­stal­la­tion of on­board dig­i­tal com­puter with sen­sors sys­tem; TV-IR tar­get auto-tracker; 30 mm grenade launcher with in­de­pen­dent electro­mechan­i­cal ver­ti­cal lay­ing drive and 300rds feed mag­a­zine; com­man­der’s panoramic sight with in­de­pen­dent LOS sta­bi­liza­tion sys­tem and in­cor­po­rat­ing op­ti­cal and laser range-find­ing chan­nels; high-pre­ci­sion dig­i­tal weapon sta­bi­lizer. The weight of add-on equip­ment in­stalled does not ex­ceed 500 kg, in­clud­ing around 260 kg of ex­tra am­mu­ni­tion: 30 mm grenades and ATGM.

Due to in­tro­duc­tion of day/night FCS the sys­tem pro- vides ac­cu­rate fir­ing with all types of weapons, in­clud­ing guided, at mov­ing and sta­tion­ary targets, round-the-clock en­gage­ment of all types of targets from sta­tion­ary po­si­tion, on the move and afloat at the range up to 4000 m with au­to­matic can­non, up to 2100 m with au­to­matic grenade launcher, up to 5500 m with 9M133-1 ATGM. Be­sides, 9M133M-2 ATGM with tan­dem shaped-charge war­head and 9M133FM ATGM with HE war­head and 9M133FM-3 ATGM with HE war­head and prox­im­ity fuse re­cently de­signed by KBP al­low fir­ing at range up to 8 km.

Kor­net-E ATGM pen­e­tra­tion ca­pa­bil­ity, in­creased up to 1100-1300 mm, al­lows re­li­able en­gage­ment of mod­ern ad­vanced tanks fit­ted with add-on ERA. Be­sides, HEF war­head of the mis­sile is able to de­stroy con­crete for­ti­fi­ca­tions and strong­points.

The im­prove­ments im­ple­mented in Kor­net ATGM en­sure: de­struc­tion of mod­ern and ad­vanced tanks tak­ing into ac­count their ar­mor pro­tec­tion growth ten­dency; en­gage­ment of any ar­mored ve­hi­cle at stand-off range; en­gage­ment of low al­ti­tude as­sault and re­con­nais­sance air­crafts in­clud­ing drones.

Be­sides, in­stal­la­tion on two sta­bi­lized launch­ers of BMP-2 ICV of four ready-to-launch guided mis­siles sig­nif­i­cantly in­crease fire rate when fir­ing ATGMs. It rules out the ne­ces­sity to reload the guided mis­sile launcher in com­bat, which in­creases the sur­vival po­ten­tial of the crew and of the en­tire com­bat ve­hi­cle.

Im­ple­men­ta­tion of TV-IR-auto tar­get tracker in­creases the ac­cu­racy of tar­get track­ing 3-6 fold in com­par­i­son with man­ual track­ing. Au­to­matic tar­get tracker adds the FCS a qual­i­ta­tively new fea­ture, putting to life the “fire-and-for­get” prin­ci­ple when fir­ing a guided mis­sile. At the same time the mis­sile cost is sig­nif­i­cantly lower than that of a mis­sile with a seeker which ful­fills the func­tion of the auto-tracker.

The pos­si­bil­ity of Kor­net ATGM launch in an el­e­vated mode al­most ex­cludes the pos­si­bil­ity of de­tect­ing the mis­sile.

Laser guid­ance mode of the ATGM with ori­en­ta­tion of the mis­sile within the laser beam pro­vides for high jam­ming-im­mu­nity against all types of ac­tive jam­ming, since the jam­mer can­not be be­hind the ICV and send the same en­coded mes­sages;

To over­come ac­tive pro­tec­tion and guar­an­teed en­gage­ment of cru­cial targets salvo launch of 2 ATGMs rid­ing on one laser beam is pro­vided.

Sig­nif­i­cant in­crease of au­to­mated gun and grenade launcher fir­ing ac­cu­racy with all types of am­mu­ni­tion is pro­vided due to the devel­op­ment of orig­i­nal fir­ing al­go­rithm. Ef­fec­tive fir­ing range of 30-mm pro­jec­tile is in­creased from 1100-1400 m up to 1800-2000 m. The prin­ci­ple of ICV ver­sa­til­ity is ful­filled by adding air de­fense ca­pac­i­ties with­out ad­di­tional ex­pen­di­tures. Ef­fec­tive en­gage­ment of per­son­nel at ranges up to 2100 is achieved due to the em­ploy­ment of low bal­lis­tics ar­ma­ments (AG-30M au­to­matic grenade launcher) with new GPD-30 rounds.

Range of ac­tiv­i­ties of CV com­man­der is in­creased due to in­stal­la­tion of night vision panoramic sight with tech­ni­cal view, im­ple­mented on ICVs for the first time. The com­man­der has all-around field of view in hori­zon and in ver­ti­cal plane the field of view is in­creased up to 60 de­grees, max­i­mal an­gu­lar ve­loc­ity of the bore sighting line in­creases from 6 to 20 deg./sec. This al­lows to in­crease the range of targets de­tected by the CV by 2.5 times, in­crease TD ac­cu­racy for the gunner by 10 times and to fully backup his tasks as well as to carry out en­gage­ment of aerial targets in au­to­matic mode. BMP-2 up­grade meets the re­quire­ments to­wards fu­ture in­fantry com­bat ve­hi­cle for the near­est 20–30 years, and up­graded BMP-3 ICV can be suc­cess­fully used till year 2030–2040.

The car­ried out up­grade fea­tures a sys­tem­atic ap­proach and leads not sim­ply to en­hance­ment of sep­a­rate tech­ni­cal specifications of the sys­tem, but has en­abled to cre­ate a ve­hi­cle with qual­i­ta­tively new fea­tures, which can suc­cess­fully com­pete with for­eign coun­ter­parts on the weapon mar­ket.

A mod­u­lar de­sign prin­ci­ple has been im­ple­mented in the com­bat com­part­ment. Thus Cus­tomer may choose re­quired set of equip­ment for in­stal­la­tion, ei­ther full or par­tial. B05Ya01 com­bat mod­ule can be also in­stalled on BMP-1 (af­ter the chas­sis is up­graded to up to the level of BMP-2), BMP-3, BMD-3 air­borne com­bat ve­hi­cle, BTR-90 APC and has passed the tri­als on their chas­sis.
