klaasmees kirjutas: ↑21 Apr, 2024 13:06Kui rünnakul on üks tank, mis tuleb nüüd ja praegu hävitada, on Javelini vs FPV droonide varu arvestus natuke tagurpidi. Kui võtta Javelini tabavustäpsuseks 0,9 ja FPV drooni puhul 0,2, siis arvutatakse möödalasu tõenäosuse järgi. (eeldusel, et tingimused laskmiseks on mõlema süsteemi jaoks võrdväärselt sobivad, praktikas tegelikult ju on plussid-miinused neil erinevad). Et siis tõenäosus, et Javelin laseb esimese pauguga mööda on 0,1, kui teine peaks otsa lastama, on tõenäosus, et mõlemad lähevad mööda 0,01. FPV drooni puhul läheb esimene lask mööda tõenäosusega 0,8. See, et ka teine pauk läheb mööda 0,64tõenäosusega. Tõenäosus, et ka kolmas mats läheb mööda, on tõenäosusega 0,512.

Ei ole. Iga matsu puhul on ikka möödalasu tõenäosus 0,9 või 0,2. Tõenäosused 0,64 ja 0,512 on keskmised 2 vastavalt 2 ja 3 korra puhul. Ehk siis, kui lasta suur hulk 2-seid või 3-seid seeriaid, siis kipub tõenäosus, et seeria kõik lasud mööda lähevad, olema selline.

The US Army's XM30 will replace the M2 Bradley from 2027. It has given General Dynamics and Rheinmetall $800 million each to develop prototypes. The OMFV program is worth $45 billion with the US Army expected to purchase some 3,800 units.

The XM30 is likely to redefine the IFV category. To this end, it will feature a 50x228 mm cannon in a remote-controlled turret. This will have twin ATGMs, advanced sensors, an AI-enabled Fire Control System, MBT-levels of protection, and a hybrid drivetrain.

XM30 will have a crew of two (driver + commander) and will carry an infantry squad of 6. A reduced capacity will ensure that the vehicle is not too large and heavy relative to Bradley. XM30 will work closely with future versions of the M1 Abrams and both vehicles will be well protected against UAS threats.

If the British Army wants a new IFV, it should consider becoming a program partner and look to acquire whichever vehicle wins the competition. Any purchase agreement should include building the vehicle in the UK with a local supply chain to support it.

Alusvankri osas siis kummiroomikud, mis teevad antud masina vibratsiooni bvs10 sarnaseks.
...

Kummiroomikute osas on mul isiklikult alati olnud mõned küsimused, millele ma häid vastuseid ei ole leidnud:
1. Kuidas need käituvad eriti käreda pakase korral (alla -20C)
2. Kuidas neid praktikas hooldatakse lahingutegevuse piirkonnas? Ajutiste metall-linkidega?
3. Kuidas nad kestavad metall-roomikutega võreldes?

Need täiskummist roomikud ei paista ka kuigi hea haarduvusega olevat, lisaks kui sõidada miinile, mis siis sellest kummist saab võrreldes metallroomikuga?

Today, Swedish and Danish defence procurement authorities have signed a contract with BAE Systems Hägglunds worth SEK25 billion to procure 205 CV 90 infantry fighting vehicles. 115 will go to , 50 to and 40 are jointly procured by and for .

BAE Systems Hägglunds, this year celebrating 125 years, has for many decades delivered innovative infantry fighting vehicles and other materiel to the Swedish Armed Forces.

The CV90 vehicles will be equipped with the latest CV90 turret and provide their crews with increased mobility, protection, and lethality. In , the Swedish CV90’s is defending Europe´s security and today’s contract will give even more strength to carry out that task.

In the Russian Federation, a material titled "Results of Research Tests of the BMP 'Bradley' M2A2 ODS SA (USA)" was published. The authors are Mushin A.V., Konyuchenko V.V., 38th Research Institute. Without delving into the details and accuracy of the figures provided by the authors, as well as the superficial nature of their comparison, I will cite several excerpts:
The BMP M2A2 ODS SA surpasses the BMP-3 in terms of projectile and bullet resistance.
In terms of mine protection, it exceeds the BMP-3 due to two aluminum and steel sheets installed on the hull bottom, an internally mounted anti-mine polymer mat, and shock-absorbing troop seats.
The side projection provides protection against a 30-mm projectile from the 3UBR6 round but does not protect against a 30-mm projectile from the 3UBR8 round.
The frontal projection provides protection against a 30-mm projectile from the 3UBR8 round, which exceeds the protection level of the BMP-3’s frontal projection.
The frontal projection with dynamic armor (ERA) blocks provides protection against cumulative grenades such as PG-9VS and PG-7VL.
The side projection with ERA blocks provides protection against cumulative grenades like PG-9VS but does not protect against grenades like PG-7VL.
The BMP M2A2 ODS SA surpasses the BMP-3 in firepower due to:
The accuracy of the 25-mm M242 automatic cannon, which is twice that of the 30-mm 2A42 and 2A72 automatic cannons, increasing the effective firing range.
The armor-piercing capability of the 25-mm APFSDS (armor-piercing fin-stabilized discarding sabot) round, which is twice that of the 30-mm APS round from the 3UBR8.
The BMP M2A2 ODS SA surpasses the BMP-3 in operational and technical characteristics due to:
The ability to access the combat compartment from the troop compartment.
Better repairability of the power unit, generator, combat compartment, and cannon barrel.
Reduced duration of technical maintenance for key components and assemblies due to easier access.
Reduced time and labor intensity for replacing key components and assemblies.
The BMP M2A2 ODS SA is inferior to the BMP-3 in terms of mobility, range, off-road capability, and the ability to ford water obstacles afloat.
The BMP M2A2 ODS SA surpasses the BMP-3 in ergonomic characteristics due to:
A larger armored volume, the presence of a ramp in the troop compartment, and the absence of structural elements between the commander’s and gunner’s workstations that hinder free movement of the crew from the combat compartment to the troop compartment.
Recommendations
Design solutions recommended for implementation in domestic serial and prospective armored combat vehicle models:
In terms of protection:
Use of protective screens, including in the frontal area, and ready-to-use ATGM (anti-tank guided missile) launchers.
Use of a commander’s protective cabin with armored glass for march operations (observation).
In terms of firepower:
Inclusion of the domestically produced 30-mm 3UBR8 round with an armor-piercing sub-caliber projectile in the ammunition load.
Development of a round with an armor-piercing fin-stabilized discarding sabot (APFSDS) projectile for 30-mm automatic cannons.
Development of a 30-mm automatic cannon with improved accuracy and armor-piercing characteristics, ensuring guaranteed defeat of BMPs like the M2A2 ODS SA (M2A3), incorporating design features found in foreign automatic cannons (e.g., barrel stiffening ribs).
